Given numbers are 211, 355, 247, 435
The list of prime factors of all numbers are
Prime factors of 211 are 211
Prime factors of 355 are 5 x 71
Prime factors of 247 are 13 x 19
Prime factors of 435 are 3 x 5 x 29
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 211, 355, 247, 435
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(211, 355) = 74905
GCD(211, 355) = ( 211 x 355 ) / 74905
= 211 / 355
= 211
Step2:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
Step3:
LCM(1, 435) = 435
GCD(1, 435) = ( 1 x 435 ) / 435
= 1 / 435
= 1
So, Greatest Common Divisor of 211, 355, 247, 435 is 1
