Given numbers are 654, 280, 646, 181
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(654, 280) = 91560
GCD(654, 280) = ( 654 x 280 ) / 91560
= 654 / 280
= 654
Step2:
LCM(2, 646) = 646
GCD(2, 646) = ( 2 x 646 ) / 646
= 2 / 646
= 2
Step3:
LCM(2, 181) = 362
GCD(2, 181) = ( 2 x 181 ) / 362
= 2 / 181
= 2
So, Greatest Common Divisor of 654, 280, 646, 181 is 1
