LCM for 31 and 33
What's the Least Common Multiple (LCM) of 31 and 33?
(One thousand, twenty-three)
Finding LCM for 31 and 33 using GCF's of these numbers
The first method to find LCM for numbers 31 and 33 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 31 and 33 is 1, so
LCM = (31 × 33) ÷ 1
LCM = 1023 ÷ 1
LCM = 1023
Finding LCM for 31 and 33 by Listing Multiples
The second method to find LCM for numbers 31 and 33 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 31: 31, 62, 93, 124, 155, 186, 217, 248, 279, 310, 341, 372, 403, 434, 465, 496, 527, 558, 589, 620, 651, 682, 713, 744, 775, 806, 837, 868, 899, 930, 961, 992, 1023, 1054, 1085
Multiples of 33: 33, 66, 99, 132, 165, 198, 231, 264, 297, 330, 363, 396, 429, 462, 495, 528, 561, 594, 627, 660, 693, 726, 759, 792, 825, 858, 891, 924, 957, 990, 1023, 1056, 1089
So the LCM for 31 and 33 is 1023
Finding LCM for 31 and 33 by Prime Factorization
Another method to find LCM for numbers 31 and 33 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 31: 31 (exponent form: 311)
All Prime Factors of 33: 3, 11 (exponent form: 31, 111)
311 × 31 × 111 = 1023
