Steps to Calculate GCD of 646, 320, 965, 272 using LCM Formula

Given numbers are 646, 320, 965, 272

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

Apply this formula for all numbers.

Step1:

LCM(646, 320) = 103360

GCD(646, 320) = ( 646 x 320 ) / 103360

= 646 / 320

= 646


Step2:

LCM(2, 965) = 1930

GCD(2, 965) = ( 2 x 965 ) / 1930

= 2 / 965

= 2


Step3:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1


So, Greatest Common Divisor of 646, 320, 965, 272 is 1
