Given numbers are 648, 255, 551, 302
The list of prime factors of all numbers are
Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3
Prime factors of 255 are 3 x 5 x 17
Prime factors of 551 are 19 x 29
Prime factors of 302 are 2 x 151
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 648, 255, 551, 302
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 255) = 55080
GCD(648, 255) = ( 648 x 255 ) / 55080
= 648 / 255
= 648
Step2:
LCM(3, 551) = 1653
GCD(3, 551) = ( 3 x 551 ) / 1653
= 3 / 551
= 3
Step3:
LCM(1, 302) = 302
GCD(1, 302) = ( 1 x 302 ) / 302
= 1 / 302
= 1
So, Greatest Common Divisor of 648, 255, 551, 302 is 1
