Given numbers are 385, 616, 921, 613
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 616) = 3080
GCD(385, 616) = ( 385 x 616 ) / 3080
= 385 / 616
= 385
Step2:
LCM(77, 921) = 70917
GCD(77, 921) = ( 77 x 921 ) / 70917
= 77 / 921
= 77
Step3:
LCM(1, 613) = 613
GCD(1, 613) = ( 1 x 613 ) / 613
= 1 / 613
= 1
So, Greatest Common Divisor of 385, 616, 921, 613 is 1
