    What's the Least Common Multiple (LCM) of 121 and 169?

    Answer

    LCM of 121 and 169 is
    20,449

    (Twenty thousand four hundred forty-nine)

    Finding LCM for 121 and 169 using GCF of these numbers

    The first method to find LCM for numbers 121 and 169 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 121 and 169 is 1, so

    LCM = (121 × 169) ÷ 1

    LCM = 20,449 ÷ 1

    LCM = 20,449

    Finding LCM for 121 and 169 by Listing Multiples

    The second method to find LCM for numbers 121 and 169 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 121: 121, 242, 363, 484, 605, 726, 847, 968, 1,089, 1,210, 1,331, 1,452, 1,573, 1,694, 1,815, 1,936, 2,057, 2,178, 2,299, 2,420, 2,541, 2,662, 2,783, 2,904, 3,025, 3,146, 3,267, 3,388, 3,509, 3,630, 3,751, 3,872, 3,993, 4,114, 4,235, 4,356, 4,477, 4,598, 4,719, 4,840, 4,961, 5,082, 5,203, 5,324, 5,445, 5,566, 5,687, 5,808, 5,929, 6,050, 6,171, 6,292, 6,413, 6,534, 6,655, 6,776, 6,897, 7,018, 7,139, 7,260, 7,381, 7,502, 7,623, 7,744, 7,865, 7,986, 8,107, 8,228, 8,349, 8,470, 8,591, 8,712, 8,833, 8,954, 9,075, 9,196, 9,317, 9,438, 9,559, 9,680, 9,801, 9,922, 10,043, 10,164, 10,285, 10,406, 10,527, 10,648, 10,769, 10,890, 11,011, 11,132, 11,253, 11,374, 11,495, 11,616, 11,737, 11,858, 11,979, 12,100, 12,221, 12,342, 12,463, 12,584, 12,705, 12,826, 12,947, 13,068, 13,189, 13,310, 13,431, 13,552, 13,673, 13,794, 13,915, 14,036, 14,157, 14,278, 14,399, 14,520, 14,641, 14,762, 14,883, 15,004, 15,125, 15,246, 15,367, 15,488, 15,609, 15,730, 15,851, 15,972, 16,093, 16,214, 16,335, 16,456, 16,577, 16,698, 16,819, 16,940, 17,061, 17,182, 17,303, 17,424, 17,545, 17,666, 17,787, 17,908, 18,029, 18,150, 18,271, 18,392, 18,513, 18,634, 18,755, 18,876, 18,997, 19,118, 19,239, 19,360, 19,481, 19,602, 19,723, 19,844, 19,965, 20,086, 20,207, 20,328, 20,449, 20,570, 20,691
