Steps to Calculate GCD of 685, 702, 87, 239 using LCM Formula
Given numbers are 685, 702, 87, 239
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 702) = 480870
GCD(685, 702) = ( 685 x 702 ) / 480870
= 685 / 702
= 685
Step2:
LCM(1, 87) = 87
GCD(1, 87) = ( 1 x 87 ) / 87
= 1 / 87
= 1
Step3:
LCM(1, 239) = 239
GCD(1, 239) = ( 1 x 239 ) / 239
= 1 / 239
= 1
So, Greatest Common Divisor of 685, 702, 87, 239 is 1
