Given numbers are 130, 880, 770, 781
The list of prime factors of all numbers are
Prime factors of 130 are 2 x 5 x 13
Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11
Prime factors of 770 are 2 x 5 x 7 x 11
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 130, 880, 770, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(130, 880) = 11440
GCD(130, 880) = ( 130 x 880 ) / 11440
= 130 / 880
= 130
Step2:
LCM(10, 770) = 770
GCD(10, 770) = ( 10 x 770 ) / 770
= 10 / 770
= 10
Step3:
LCM(10, 781) = 7810
GCD(10, 781) = ( 10 x 781 ) / 7810
= 10 / 781
= 10
So, Greatest Common Divisor of 130, 880, 770, 781 is 1
