(Four hundred twenty-nine)
Finding LCM for 33 and 39 using GCF's of these numbers
The first method to find LCM for numbers 33 and 39 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 33 and 39 is 3, so
LCM = (33 × 39) ÷ 3
LCM = 1287 ÷ 3
LCM = 429
Finding LCM for 33 and 39 by Listing Multiples
The second method to find LCM for numbers 33 and 39 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 33: 33, 66, 99, 132, 165, 198, 231, 264, 297, 330, 363, 396, 429, 462, 495
Multiples of 39: 39, 78, 117, 156, 195, 234, 273, 312, 351, 390, 429, 468, 507
So the LCM for 33 and 39 is 429
Finding LCM for 33 and 39 by Prime Factorization
Another method to find LCM for numbers 33 and 39 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 33: 3, 11 (exponent form: 31, 111)
All Prime Factors of 39: 3, 13 (exponent form: 31, 131)
31 × 111 × 131 = 429
