Given numbers are 680, 162, 136, 231
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 162) = 55080
GCD(680, 162) = ( 680 x 162 ) / 55080
= 680 / 162
= 680
Step2:
LCM(2, 136) = 136
GCD(2, 136) = ( 2 x 136 ) / 136
= 2 / 136
= 2
Step3:
LCM(2, 231) = 462
GCD(2, 231) = ( 2 x 231 ) / 462
= 2 / 231
= 2
So, Greatest Common Divisor of 680, 162, 136, 231 is 1
