Steps to Calculate GCD of 428, 112, 81, 611 using LCM Formula
Given numbers are 428, 112, 81, 611
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 112) = 11984
GCD(428, 112) = ( 428 x 112 ) / 11984
= 428 / 112
= 428
Step2:
LCM(4, 81) = 324
GCD(4, 81) = ( 4 x 81 ) / 324
= 4 / 81
= 4
Step3:
LCM(1, 611) = 611
GCD(1, 611) = ( 1 x 611 ) / 611
= 1 / 611
= 1
So, Greatest Common Divisor of 428, 112, 81, 611 is 1
