Steps to Calculate GCD of 621, 615, 163, 347 using LCM Formula
Given numbers are 621, 615, 163, 347
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 615) = 127305
GCD(621, 615) = ( 621 x 615 ) / 127305
= 621 / 615
= 621
Step2:
LCM(3, 163) = 489
GCD(3, 163) = ( 3 x 163 ) / 489
= 3 / 163
= 3
Step3:
LCM(1, 347) = 347
GCD(1, 347) = ( 1 x 347 ) / 347
= 1 / 347
= 1
So, Greatest Common Divisor of 621, 615, 163, 347 is 1
