The list of prime factors of all numbers are
Prime factors of 706 are 2 x 353
Prime factors of 357 are 3 x 7 x 17
Prime factors of 408 are 2 x 2 x 2 x 3 x 17
Prime factors of 438 are 2 x 3 x 73
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 706, 357, 408, 438
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(706, 357) = 252042
GCD(706, 357) = ( 706 x 357 ) / 252042
= 706 / 357
= 706
Step2:
LCM(1, 408) = 408
GCD(1, 408) = ( 1 x 408 ) / 408
= 1 / 408
= 1
Step3:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
So, Greatest Common Divisor of 706, 357, 408, 438 is 1
