Given numbers are 620, 187, 330, 780
The list of prime factors of all numbers are
Prime factors of 620 are 2 x 2 x 5 x 31
Prime factors of 187 are 11 x 17
Prime factors of 330 are 2 x 3 x 5 x 11
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 620, 187, 330, 780
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 187) = 115940
GCD(620, 187) = ( 620 x 187 ) / 115940
= 620 / 187
= 620
Step2:
LCM(1, 330) = 330
GCD(1, 330) = ( 1 x 330 ) / 330
= 1 / 330
= 1
Step3:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
So, Greatest Common Divisor of 620, 187, 330, 780 is 1
