Steps to Calculate GCD of 239, 621, 31, 280 using LCM Formula
Given numbers are 239, 621, 31, 280
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(239, 621) = 148419
GCD(239, 621) = ( 239 x 621 ) / 148419
= 239 / 621
= 239
Step2:
LCM(1, 31) = 31
GCD(1, 31) = ( 1 x 31 ) / 31
= 1 / 31
= 1
Step3:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
So, Greatest Common Divisor of 239, 621, 31, 280 is 1
