Least common multiple (LCM) of 15, 77, 61, 7, 61 is 70455.

LCM(15, 77, 61, 7, 61) = 70455

LCM of 15, 77, 61, 7, 61

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

Least Common Multiple of 15, 77, 61, 7, 61 by common division method
Least Common Multiple of 15, 77, 61, 7, 61 with GCF Formula

Least Common Multiple of 15,77,61,7,61

Least Common Multiple (LCM) of 15,77,61,7,61 is 70455

7	15, 77, 61, 7, 61
61	15, 11, 61, 1, 61
	15, 11, 1, 1, 1

∴ So the LCM of the given numbers is 7 x 61 x 15 x 11 x 1 x 1 x 1 = 70455

Least Common Multiple of 15,77,61,7,61 with GCF Formula

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 15,77,61,7,61 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(15,77,61,7,61) = 1

common factors(in case of two or more numbers have common factors) = 427

GCF(15,77,61,7,61) x common factors =1 x 427 = 427

LCM(15,77,61,7,61) = ( 15 × 77 × 61 × 7 × 61 ) / 427

LCM(15,77,61,7,61) = 30084285 / 427

LCM(15,77,61,7,61) = 70455

∴ Least Common Multiple of 15,77,61,7,61 is 70455
