Steps to Calculate GCD of 331, 308, 388, 428 using LCM Formula
Given numbers are 331, 308, 388, 428
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(331, 308) = 101948
GCD(331, 308) = ( 331 x 308 ) / 101948
= 331 / 308
= 331
Step2:
LCM(1, 388) = 388
GCD(1, 388) = ( 1 x 388 ) / 388
= 1 / 388
= 1
Step3:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
So, Greatest Common Divisor of 331, 308, 388, 428 is 1
