Given numbers are 685, 220, 953, 171
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 220) = 30140
GCD(685, 220) = ( 685 x 220 ) / 30140
= 685 / 220
= 685
Step2:
LCM(5, 953) = 4765
GCD(5, 953) = ( 5 x 953 ) / 4765
= 5 / 953
= 5
Step3:
LCM(1, 171) = 171
GCD(1, 171) = ( 1 x 171 ) / 171
= 1 / 171
= 1
So, Greatest Common Divisor of 685, 220, 953, 171 is 1
