1056. 24 = 23 x 3 32 = 25 44 = 22 x 11 lcm = 25 x 3 x 11 = 1056
72 = 23 x 32 24 = 23 x 3 16 = 24 The LCM of 72, 24, and 16 is 24 x 32 = 144.
To solve the LCM of 180 and 252, factor them in their prime factors...180 = 2 * 2 * 3 * 3 * 5 = 22 * 32 * 51252 = 2 * 2 * 3 * 3 * 7 = 22 * 32 * 71... then multiply the prime factors with the highest power together...22 * 32 * 51 * 71 = 1260180 and 252 is a simple example which does not completely illustrate the priniciple involved. A better example might be 48 and 180...48 = 2 * 2 * 2 * 2 * 3 = 24 * 31180 = 2 * 2 * 3 * 3 * 5 = 22 * 32 * 51... so the LCM would be 24 * 32 * 51 = 720
1764. 98 = 2 x 72 36 = 22 x 32 42 = 2 x 3 x 7 lcm = 22 x 32 x 72 = 1764
It can be. 69 is the GCF of 138 and 207.
2520. 84 = 22 x 3 x 7 360 = 23 x 32 x 5 lcm = 23 x 32 x 5 x 7 = 2520
1800 200 = 23 x 52 300 = 22 x 3 x 52 450 = 2 x 32 x 52 600 = 23 x 3 x 52 lcm = 23 x 32 x 52 = 1800
Prime factorization: 84 = 22 x 3 x 7 360 = 23 x 32 x 5 The LCM of 84 and 360 is 23 x 32 x 5 x 7 = 2,520.
18 in pime exponents is 2*32 24 in prime exponents is 23*3 LCM: 23*32 = 72
lcm(48, 72) = 144 48 = 24 x 3 72 = 23 x 32 lcm = 24 x 32 = 144
252. 12 = 22 x 3 14 = 2 x 7 36 = 22 x 32 lcm = 22 x 32 x 7 = 252
prime factors of 18 are 2 and 32 prime factors of 24 are 23 and 3 prime factors of 42 are 2, 3 and 7 LCM = 23*32*7 = 504
The LCM is 96.
180. 90 = 2 x 32 x 5 60 = 22 x 3 x 5 lcm = 22 x 32 x 5 = 180
lcm(72, 96, 192) = 576 72 = 23 x 32 96 = 25 x 3 192 = 26 x 3 lcm = 26 x 32 = 576
