What's the Least Common Multiple (LCM) of 100 and 155?

Answer

LCM of 100 and 155 is 3,100

(Three thousand, one hundred)

Finding LCM for 100 and 155 using GCF of these numbers

The first method to find LCM for numbers 100 and 155 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 100 and 155 is 5, so

LCM = (100 × 155) ÷ 5

LCM = 15500 ÷ 5

LCM = 3100

Finding LCM for 100 and 155 by Listing Multiples

The second method to find LCM for numbers 100 and 155 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 100: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000, 2100, 2200, 2300, 2400, 2500, 2600, 2700, 2800, 2900, 3000, 3100, 3200, 3300

Multiples of 155: 155, 310, 465, 620, 775, 930, 1085, 1240, 1395, 1550, 1705, 1860, 2015, 2170, 2325, 2480, 2635, 2790, 2945, 3100, 3255, 3410

So the LCM for 100 and 155 is 3100

Finding LCM for 100 and 155 by Prime Factorization

Another method to find LCM for numbers 100 and 155 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 100: 2, 2, 5, 5 (exponent form: 22, 52)

All Prime Factors of 155: 5, 31 (exponent form: 51, 311)

22 × 52 × 311 = 3100
