Steps to Calculate GCD of 247, 277, 419, 628 using LCM Formula

Given numbers are 247, 277, 419, 628

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

Apply this formula for all numbers.

Step1:

LCM(247, 277) = 68419

GCD(247, 277) = ( 247 x 277 ) / 68419

= 247 / 277

= 247


Step2:

LCM(1, 419) = 419

GCD(1, 419) = ( 1 x 419 ) / 419

= 1 / 419

= 1


Step3:

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

= 1 / 628

= 1


So, Greatest Common Divisor of 247, 277, 419, 628 is 1
