The list of prime factors of all numbers are
Prime factors of 650 are 2 x 5 x 5 x 13
Prime factors of 505 are 5 x 101
Prime factors of 391 are 17 x 23
Prime factors of 771 are 3 x 257
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 650, 505, 391, 771
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(650, 505) = 65650
GCD(650, 505) = ( 650 x 505 ) / 65650
= 650 / 505
= 650
Step2:
LCM(5, 391) = 1955
GCD(5, 391) = ( 5 x 391 ) / 1955
= 5 / 391
= 5
Step3:
LCM(1, 771) = 771
GCD(1, 771) = ( 1 x 771 ) / 771
= 1 / 771
= 1
So, Greatest Common Divisor of 650, 505, 391, 771 is 1
