Prime factors of 685 are 5 x 137
Prime factors of 630 are 2 x 3 x 3 x 5 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 766, 154, 685, 630
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(766, 154) = 58982
GCD(766, 154) = ( 766 x 154 ) / 58982
= 766 / 154
= 766
Step2:
LCM(2, 685) = 1370
GCD(2, 685) = ( 2 x 685 ) / 1370
= 2 / 685
= 2
Step3:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
So, Greatest Common Divisor of 766, 154, 685, 630 is 1
