Prime factors of 430 are 2 x 5 x 43
Prime factors of 855 are 3 x 3 x 5 x 19
Prime factors of 272 are 2 x 2 x 2 x 2 x 17
Prime factors of 274 are 2 x 137
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 430, 855, 272, 274
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 855) = 73530
GCD(430, 855) = ( 430 x 855 ) / 73530
= 430 / 855
= 430
Step2:
LCM(5, 272) = 1360
GCD(5, 272) = ( 5 x 272 ) / 1360
= 5 / 272
= 5
Step3:
LCM(1, 274) = 274
GCD(1, 274) = ( 1 x 274 ) / 274
= 1 / 274
= 1
So, Greatest Common Divisor of 430, 855, 272, 274 is 1
