Steps to Calculate GCD of 51, 94, 28, 20 using LCM Formula

Given numbers are 51, 94, 28, 20

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

Apply this formula for all numbers.

Step1:

LCM(51, 94) = 4794

GCD(51, 94) = ( 51 x 94 ) / 4794

= 51 / 94

= 51


Step2:

LCM(1, 28) = 28

GCD(1, 28) = ( 1 x 28 ) / 28

= 1 / 28

= 1


Step3:

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

= 1 / 20

= 1


So, Greatest Common Divisor of 51, 94, 28, 20 is 1
