Given numbers are 646, 320, 965, 272
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 320) = 103360
GCD(646, 320) = ( 646 x 320 ) / 103360
= 646 / 320
= 646
Step2:
LCM(2, 965) = 1930
GCD(2, 965) = ( 2 x 965 ) / 1930
= 2 / 965
= 2
Step3:
LCM(1, 272) = 272
GCD(1, 272) = ( 1 x 272 ) / 272
= 1 / 272
= 1
So, Greatest Common Divisor of 646, 320, 965, 272 is 1
