Given numbers are 511, 920, 420, 102
The list of prime factors of all numbers are
Prime factors of 511 are 7 x 73
Prime factors of 920 are 2 x 2 x 2 x 5 x 23
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 102 are 2 x 3 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 511, 920, 420, 102
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(511, 920) = 470120
GCD(511, 920) = ( 511 x 920 ) / 470120
= 511 / 920
= 511
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 102) = 102
GCD(1, 102) = ( 1 x 102 ) / 102
= 1 / 102
= 1
So, Greatest Common Divisor of 511, 920, 420, 102 is 1
