Given numbers are 128, 236, 506, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(128, 236) = 7552
GCD(128, 236) = ( 128 x 236 ) / 7552
= 128 / 236
= 128
Step2:
LCM(4, 506) = 1012
GCD(4, 506) = ( 4 x 506 ) / 1012
= 4 / 506
= 4
Step3:
LCM(2, 865) = 1730
GCD(2, 865) = ( 2 x 865 ) / 1730
= 2 / 865
= 2
So, Greatest Common Divisor of 128, 236, 506, 865 is 1
