Prime factors of 157 are 157
Prime factors of 782 are 2 x 17 x 23
Prime factors of 545 are 5 x 109
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 780, 157, 782, 545
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 157) = 122460
GCD(780, 157) = ( 780 x 157 ) / 122460
= 780 / 157
= 780
Step2:
LCM(1, 782) = 782
GCD(1, 782) = ( 1 x 782 ) / 782
= 1 / 782
= 1
Step3:
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
= 1 / 545
= 1
So, Greatest Common Divisor of 780, 157, 782, 545 is 1
