Prime factors of 779 are 19 x 41
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 400, 698, 547, 779
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 698) = 139600
GCD(400, 698) = ( 400 x 698 ) / 139600
= 400 / 698
= 400
Step2:
LCM(2, 547) = 1094
GCD(2, 547) = ( 2 x 547 ) / 1094
= 2 / 547
= 2
Step3:
LCM(1, 779) = 779
GCD(1, 779) = ( 1 x 779 ) / 779
= 1 / 779
= 1
So, Greatest Common Divisor of 400, 698, 547, 779 is 1
