Given numbers are 272, 396, 781, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(272, 396) = 26928
GCD(272, 396) = ( 272 x 396 ) / 26928
= 272 / 396
= 272
Step2:
LCM(4, 781) = 3124
GCD(4, 781) = ( 4 x 781 ) / 3124
= 4 / 781
= 4
Step3:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
So, Greatest Common Divisor of 272, 396, 781, 865 is 1
