Given numbers are 154, 616, 561, 907
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(154, 616) = 616
GCD(154, 616) = ( 154 x 616 ) / 616
= 154 / 616
= 154
Step2:
LCM(154, 561) = 7854
GCD(154, 561) = ( 154 x 561 ) / 7854
= 154 / 561
= 154
Step3:
LCM(11, 907) = 9977
GCD(11, 907) = ( 11 x 907 ) / 9977
= 11 / 907
= 11
So, Greatest Common Divisor of 154, 616, 561, 907 is 1
