The list of prime factors of all numbers are
Prime factors of 213 are 3 x 71
Prime factors of 346 are 2 x 173
Prime factors of 435 are 3 x 5 x 29
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 213, 346, 435, 780
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 346) = 73698
GCD(213, 346) = ( 213 x 346 ) / 73698
= 213 / 346
= 213
Step2:
LCM(1, 435) = 435
GCD(1, 435) = ( 1 x 435 ) / 435
= 1 / 435
= 1
Step3:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
So, Greatest Common Divisor of 213, 346, 435, 780 is 1
