Given numbers are 730, 128, 121, 254
The list of prime factors of all numbers are
Prime factors of 730 are 2 x 5 x 73
Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2
Prime factors of 121 are 11 x 11
Prime factors of 254 are 2 x 127
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 730, 128, 121, 254
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(730, 128) = 46720
GCD(730, 128) = ( 730 x 128 ) / 46720
= 730 / 128
= 730
Step2:
LCM(2, 121) = 242
GCD(2, 121) = ( 2 x 121 ) / 242
= 2 / 121
= 2
Step3:
LCM(1, 254) = 254
GCD(1, 254) = ( 1 x 254 ) / 254
= 1 / 254
= 1
So, Greatest Common Divisor of 730, 128, 121, 254 is 1
