The list of prime factors of all numbers are
Prime factors of 851 are 23 x 37
Prime factors of 753 are 3 x 251
Prime factors of 545 are 5 x 109
Prime factors of 780 are 2 x 2 x 3 x 5 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 851, 753, 545, 780
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(851, 753) = 640803
GCD(851, 753) = ( 851 x 753 ) / 640803
= 851 / 753
= 851
Step2:
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
= 1 / 545
= 1
Step3:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
So, Greatest Common Divisor of 851, 753, 545, 780 is 1
