Steps to Calculate GCD of 247, 656, 427, 666 using LCM Formula

Given numbers are 247, 656, 427, 666

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(247, 656) = 162032

GCD(247, 656) = ( 247 x 656 ) / 162032

= 247 / 656

= 247


Step2:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1


Step3:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1


So, Greatest Common Divisor of 247, 656, 427, 666 is 1
