Given numbers are 780, 705, 210, 416
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 705 are 3 x 5 x 47
Prime factors of 210 are 2 x 3 x 5 x 7
Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 780, 705, 210, 416
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 705) = 36660
GCD(780, 705) = ( 780 x 705 ) / 36660
= 780 / 705
= 780
Step2:
LCM(15, 210) = 210
GCD(15, 210) = ( 15 x 210 ) / 210
= 15 / 210
= 15
Step3:
LCM(15, 416) = 6240
GCD(15, 416) = ( 15 x 416 ) / 6240
= 15 / 416
= 15
So, Greatest Common Divisor of 780, 705, 210, 416 is 1
