Given numbers are 770, 538, 517, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 538) = 207130
GCD(770, 538) = ( 770 x 538 ) / 207130
= 770 / 538
= 770
Step2:
LCM(2, 517) = 1034
GCD(2, 517) = ( 2 x 517 ) / 1034
= 2 / 517
= 2
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 770, 538, 517, 638 is 1
