Steps to Calculate GCD of 56, 68, 79, 49 using LCM Formula

Given numbers are 56, 68, 79, 49

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

Apply this formula for all numbers.

Step1:

LCM(56, 68) = 952

GCD(56, 68) = ( 56 x 68 ) / 952

= 56 / 68

= 56


Step2:

LCM(4, 79) = 316

GCD(4, 79) = ( 4 x 79 ) / 316

= 4 / 79

= 4


Step3:

LCM(1, 49) = 49

GCD(1, 49) = ( 1 x 49 ) / 49

= 1 / 49

= 1


So, Greatest Common Divisor of 56, 68, 79, 49 is 1
