Steps to Calculate GCD of 56, 20, 64, 20 using LCM Formula

Given numbers are 56, 20, 64, 20

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

Apply this formula for all numbers.

Step1:

LCM(56, 20) = 280

GCD(56, 20) = ( 56 x 20 ) / 280

= 56 / 20

= 56


Step2:

LCM(4, 64) = 64

GCD(4, 64) = ( 4 x 64 ) / 64

= 4 / 64

= 4


Step3:

LCM(4, 20) = 20

GCD(4, 20) = ( 4 x 20 ) / 20

= 4 / 20

= 4


So, Greatest Common Divisor of 56, 20, 64, 20 is 4
