Steps to Calculate GCD of 642, 307, 274, 123 using LCM Formula

Given numbers are 642, 307, 274, 123

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

Apply this formula for all numbers.

Step1:

LCM(642, 307) = 197094

GCD(642, 307) = ( 642 x 307 ) / 197094

= 642 / 307

= 642


Step2:

LCM(1, 274) = 274

GCD(1, 274) = ( 1 x 274 ) / 274

= 1 / 274

= 1


Step3:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1


So, Greatest Common Divisor of 642, 307, 274, 123 is 1
