What's the Least Common Multiple (LCM) of 98 and 105?

Answer

LCM of 98 and 105 is
1,470

(One thousand four hundred seventy)

Finding LCM for 98 and 105 using GCF of these numbers

The first method to find LCM for numbers 98 and 105 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 98 and 105 is 7, so

LCM = (98 × 105) ÷ 7

LCM = 10,290 ÷ 7

LCM = 1,470

Finding LCM for 98 and 105 by Listing Multiples

The second method to find LCM for numbers 98 and 105 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 98: 98, 196, 294, 392, 490, 588, 686, 784, 882, 980, 1,078, 1,176, 1,274, 1,372, 1,470, 1,568, 1,666

Multiples of 105: 105, 210, 315, 420, 525, 630, 735, 840, 945, 1,050, 1,155, 1,260, 1,365, 1,470, 1,575, 1,680

So the LCM for 98 and 105 is 1,470

Finding LCM for 98 and 105 by Prime Factorization

Another method to find LCM for numbers 98 and 105 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 98: 2, 7, 7 (exponent form: 21, 72)

All Prime Factors of 105: 3, 5, 7 (exponent form: 31, 51, 71)

21 × 72 × 31 × 51 = 1,470
