Steps to Calculate GCD of 685, 247, 461, 202 using LCM Formula
Given numbers are 685, 247, 461, 202
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 247) = 169195
GCD(685, 247) = ( 685 x 247 ) / 169195
= 685 / 247
= 685
Step2:
LCM(1, 461) = 461
GCD(1, 461) = ( 1 x 461 ) / 461
= 1 / 461
= 1
Step3:
LCM(1, 202) = 202
GCD(1, 202) = ( 1 x 202 ) / 202
= 1 / 202
= 1
So, Greatest Common Divisor of 685, 247, 461, 202 is 1
