Steps to Calculate GCD of 76, 21, 87, 83 using LCM Formula
Given numbers are 76, 21, 87, 83
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(76, 21) = 1596
GCD(76, 21) = ( 76 x 21 ) / 1596
= 76 / 21
= 76
Step2:
LCM(1, 87) = 87
GCD(1, 87) = ( 1 x 87 ) / 87
= 1 / 87
= 1
Step3:
LCM(1, 83) = 83
GCD(1, 83) = ( 1 x 83 ) / 83
= 1 / 83
= 1
So, Greatest Common Divisor of 76, 21, 87, 83 is 1
