Least Common Multiple of 642, 690

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

• Least Common Multiple of 642, 690 by common division method
• Least Common Multiple of 642, 690 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 107 x 115 = 73830

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 642,690 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(642,690) = 6

common factors(in case of two or more numbers have common factors) = 1

GCF(642,690) x common factors =6 x 1 = 6

LCM(642,690) = ( 642 × 690 ) / 6

LCM(642,690) = 442980 / 6

LCM(642,690) = 73830

∴ Least Common Multiple of 642,690 is 73830

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

• LCM of 720, 597
• LCM of 946, 389
• LCM of 277, 799
• LCM of 742, 738
• LCM of 346, 335
