Answer

LCM of 30 and 450 is 450

(Four hundred fifty)

Finding LCM for 30 and 450 using GCF of these numbers

The first method to find LCM for numbers 30 and 450 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 30 and 450 is 30, so

LCM = (30 × 450) ÷ 30

LCM = 13500 ÷ 30

LCM = 450

Finding LCM for 30 and 450 by Listing Multiples

The second method to find LCM for numbers 30 and 450 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 30: 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360, 390, 420, 450, 480, 510

Multiples of 450: 450, 900, 1350

So the LCM for 30 and 450 is 450

Finding LCM for 30 and 450 by Prime Factorization

Another method to find LCM for numbers 30 and 450 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 30: 2, 3, 5 (exponent form: 21, 31, 51)

All Prime Factors of 450: 2, 3, 3, 5, 5 (exponent form: 21, 32, 52)

21 × 32 × 52 = 450
