What's the Least Common Multiple (LCM) of 100 and 190?

Answer

LCM of 100 and 190 is 1,900

(One thousand, nine hundred)

Finding LCM for 100 and 190 using GCF of these numbers

The first method to find LCM for numbers 100 and 190 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 100 and 190 is 10, so

LCM = (100 × 190) ÷ 10

LCM = 19000 ÷ 10

LCM = 1900

Finding LCM for 100 and 190 by Listing Multiples

The second method to find LCM for numbers 100 and 190 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

Multiples of 190: 190, 380, 570, 760, 950, 1140, 1330, 1520, 1710, 1900, 2090, 2280

So the LCM for 100 and 190 is 1900

Finding LCM for 100 and 190 by Prime Factorization

Another method to find LCM for numbers 100 and 190 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 190: 2, 5, 19 (exponent form: 21, 51, 191)

22 × 52 × 191 = 1900
