Given numbers are 430, 128, 865, 616
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 128) = 27520
GCD(430, 128) = ( 430 x 128 ) / 27520
= 430 / 128
= 430
Step2:
LCM(2, 865) = 1730
GCD(2, 865) = ( 2 x 865 ) / 1730
= 2 / 865
= 2
Step3:
LCM(1, 616) = 616
GCD(1, 616) = ( 1 x 616 ) / 616
= 1 / 616
= 1
So, Greatest Common Divisor of 430, 128, 865, 616 is 1
