Given numbers are 880, 255, 980, 781
The list of prime factors of all numbers are
Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11
Prime factors of 255 are 3 x 5 x 17
Prime factors of 980 are 2 x 2 x 5 x 7 x 7
Prime factors of 781 are 11 x 71
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 880, 255, 980, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(880, 255) = 44880
GCD(880, 255) = ( 880 x 255 ) / 44880
= 880 / 255
= 880
Step2:
LCM(5, 980) = 980
GCD(5, 980) = ( 5 x 980 ) / 980
= 5 / 980
= 5
Step3:
LCM(5, 781) = 3905
GCD(5, 781) = ( 5 x 781 ) / 3905
= 5 / 781
= 5
So, Greatest Common Divisor of 880, 255, 980, 781 is 1
