Finding LCM for 22 and 45 using GCF's of these numbers
The first method to find LCM for numbers 22 and 45 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 22 and 45 is 1, so
LCM = (22 × 45) ÷ 1
LCM = 990 ÷ 1
LCM = 990
Finding LCM for 22 and 45 by Listing Multiples
The second method to find LCM for numbers 22 and 45 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 22: 22, 44, 66, 88, 110, 132, 154, 176, 198, 220, 242, 264, 286, 308, 330, 352, 374, 396, 418, 440, 462, 484, 506, 528, 550, 572, 594, 616, 638, 660, 682, 704, 726, 748, 770, 792, 814, 836, 858, 880, 902, 924, 946, 968, 990, 1012, 1034
Multiples of 45: 45, 90, 135, 180, 225, 270, 315, 360, 405, 450, 495, 540, 585, 630, 675, 720, 765, 810, 855, 900, 945, 990, 1035, 1080
So the LCM for 22 and 45 is 990
