LCM for 4 and 46
What's the Least Common Multiple (LCM) of 4 and 46?
Answer
(Ninety-two)
Finding LCM for 4 and 46 using GCF of these numbers
The first method to find LCM for numbers 4 and 46 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 4 and 46 is 2, so
LCM = (4 × 46) ÷ 2
LCM = 184 ÷ 2
LCM = 92
Finding LCM for 4 and 46 by Listing Multiples
The second method to find LCM for numbers 4 and 46 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96, 100
Multiples of 46: 46, 92, 138, 184
So the LCM for 4 and 46 is 92
Finding LCM for 4 and 46 by Prime Factorization
Another method to find LCM for numbers 4 and 46 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 4: 2, 2 (exponent form: 22)
All Prime Factors of 46: 2, 23 (exponent form: 21, 231)
22 × 231 = 92
