Prime factors of 455 are 5 x 7 x 13
Prime factors of 270 are 2 x 3 x 3 x 3 x 5
Prime factors of 510 are 2 x 3 x 5 x 17
Prime factors of 678 are 2 x 3 x 113
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 455, 270, 510, 678
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 270) = 24570
GCD(455, 270) = ( 455 x 270 ) / 24570
= 455 / 270
= 455
Step2:
LCM(5, 510) = 510
GCD(5, 510) = ( 5 x 510 ) / 510
= 5 / 510
= 5
Step3:
LCM(5, 678) = 3390
GCD(5, 678) = ( 5 x 678 ) / 3390
= 5 / 678
= 5
So, Greatest Common Divisor of 455, 270, 510, 678 is 1
