Finding LCM for 11 and 45 using GCF of these numbers
The first method to find LCM for numbers 11 and 45 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 11 and 45 is 1, so
LCM = (11 × 45) ÷ 1
LCM = 495 ÷ 1
LCM = 495
Finding LCM for 11 and 45 by Listing Multiples
The second method to find LCM for numbers 11 and 45 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 11: 11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121, 132, 143, 154, 165, 176, 187, 198, 209, 220, 231, 242, 253, 264, 275, 286, 297, 308, 319, 330, 341, 352, 363, 374, 385, 396, 407, 418, 429, 440, 451, 462, 473, 484, 495, 506, 517
Multiples of 45: 45, 90, 135, 180, 225, 270, 315, 360, 405, 450, 495, 540, 585
So the LCM for 11 and 45 is 495
Finding LCM for 11 and 45 by Prime Factorization
Another method to find LCM for numbers 11 and 45 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 11: 11 (exponent form: 111)
All Prime Factors of 45: 3, 3, 5 (exponent form: 32, 51)
111 × 32 × 51 = 495
