Steps to Calculate GCD of 48, 49, 21, 68 using LCM Formula
Given numbers are 48, 49, 21, 68
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(48, 49) = 2352
GCD(48, 49) = ( 48 x 49 ) / 2352
= 48 / 49
= 48
Step2:
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
= 1 / 21
= 1
Step3:
LCM(1, 68) = 68
GCD(1, 68) = ( 1 x 68 ) / 68
= 1 / 68
= 1
So, Greatest Common Divisor of 48, 49, 21, 68 is 1
