The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 648, 770, 355, 113
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 770) = 249480
GCD(648, 770) = ( 648 x 770 ) / 249480
= 648 / 770
= 648
Step2:
LCM(2, 355) = 710
GCD(2, 355) = ( 2 x 355 ) / 710
= 2 / 355
= 2
Step3:
LCM(1, 113) = 113
GCD(1, 113) = ( 1 x 113 ) / 113
= 1 / 113
= 1
So, Greatest Common Divisor of 648, 770, 355, 113 is 1
