Given numbers are 400, 170, 340, 357
The list of prime factors of all numbers are
Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5
Prime factors of 170 are 2 x 5 x 17
Prime factors of 340 are 2 x 2 x 5 x 17
Prime factors of 357 are 3 x 7 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 400, 170, 340, 357
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 170) = 6800
GCD(400, 170) = ( 400 x 170 ) / 6800
= 400 / 170
= 400
Step2:
LCM(10, 340) = 340
GCD(10, 340) = ( 10 x 340 ) / 340
= 10 / 340
= 10
Step3:
LCM(10, 357) = 3570
GCD(10, 357) = ( 10 x 357 ) / 3570
= 10 / 357
= 10
So, Greatest Common Divisor of 400, 170, 340, 357 is 1
