Steps to Calculate GCD of 760, 621, 353, 420 using LCM Formula

Given numbers are 760, 621, 353, 420

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

Apply this formula for all numbers.

Step1:

LCM(760, 621) = 471960

GCD(760, 621) = ( 760 x 621 ) / 471960

= 760 / 621

= 760


Step2:

LCM(1, 353) = 353

GCD(1, 353) = ( 1 x 353 ) / 353

= 1 / 353

= 1


Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1


So, Greatest Common Divisor of 760, 621, 353, 420 is 1
