Steps to Calculate GCD of 77, 16, 57, 99 using LCM Formula
Given numbers are 77, 16, 57, 99
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(77, 16) = 1232
GCD(77, 16) = ( 77 x 16 ) / 1232
= 77 / 16
= 77
Step2:
LCM(1, 57) = 57
GCD(1, 57) = ( 1 x 57 ) / 57
= 1 / 57
= 1
Step3:
LCM(1, 99) = 99
GCD(1, 99) = ( 1 x 99 ) / 99
= 1 / 99
= 1
So, Greatest Common Divisor of 77, 16, 57, 99 is 1
