The list of prime factors of all numbers are
Prime factors of 698 are 2 x 349
Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7
Prime factors of 430 are 2 x 5 x 43
Prime factors of 745 are 5 x 149
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 698, 756, 430, 745
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(698, 756) = 263844
GCD(698, 756) = ( 698 x 756 ) / 263844
= 698 / 756
= 698
Step2:
LCM(2, 430) = 430
GCD(2, 430) = ( 2 x 430 ) / 430
= 2 / 430
= 2
Step3:
LCM(2, 745) = 1490
GCD(2, 745) = ( 2 x 745 ) / 1490
= 2 / 745
= 2
So, Greatest Common Divisor of 698, 756, 430, 745 is 1
