Given numbers are 780, 107, 105, 202
The list of prime factors of all numbers are
Prime factors of 780 are 2 x 2 x 3 x 5 x 13
Prime factors of 107 are 107
Prime factors of 105 are 3 x 5 x 7
Prime factors of 202 are 2 x 101
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 780, 107, 105, 202
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 107) = 83460
GCD(780, 107) = ( 780 x 107 ) / 83460
= 780 / 107
= 780
Step2:
LCM(1, 105) = 105
GCD(1, 105) = ( 1 x 105 ) / 105
= 1 / 105
= 1
Step3:
LCM(1, 202) = 202
GCD(1, 202) = ( 1 x 202 ) / 202
= 1 / 202
= 1
So, Greatest Common Divisor of 780, 107, 105, 202 is 1
