Least Common Multiple of 689, 8420

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

• Least Common Multiple of 689, 8420 by common division method
• Least Common Multiple of 689, 8420 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 5801380

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 689,8420 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(689,8420) = 1

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

GCF(689,8420) x common factors =1 x 1 = 1

LCM(689,8420) = ( 689 × 8420 ) / 1

LCM(689,8420) = 5801380 / 1

LCM(689,8420) = 5801380

∴ Least Common Multiple of 689,8420 is 5801380

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

• LCM of 277, 2449
• LCM of 788, 2502
• LCM of 329, 9563
• LCM of 474, 6879
• LCM of 558, 7147
