Least Common Multiple of 155, 237, 21

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

• Least Common Multiple of 155, 237, 21 by common division method
• Least Common Multiple of 155, 237, 21 with GCF Formula

∴ So the LCM of the given numbers is 3 x 155 x 79 x 7 = 257145

The formula of LCM is LCM(a₁,a₂,a₃....,a_n) = ( a₁ × a₂ × a₃ × .... × a_n) / GCF(a₁,a₂,a₃....,a_n) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 155,237,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(155,237,21) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(155,237,21) x common factors =1 x 3 = 3

LCM(155,237,21) = ( 155 × 237 × 21 ) / 3

LCM(155,237,21) = 771435 / 3

LCM(155,237,21) = 257145

∴ Least Common Multiple of 155,237,21 is 257145

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 776, 892, 81
• LCM of 824, 290, 28
• LCM of 203, 955, 86
