Given numbers are 512, 120, 620, 215
The list of prime factors of all numbers are
Prime factors of 512 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2
Prime factors of 120 are 2 x 2 x 2 x 3 x 5
Prime factors of 620 are 2 x 2 x 5 x 31
Prime factors of 215 are 5 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 512, 120, 620, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(512, 120) = 7680
GCD(512, 120) = ( 512 x 120 ) / 7680
= 512 / 120
= 512
Step2:
LCM(8, 620) = 1240
GCD(8, 620) = ( 8 x 620 ) / 1240
= 8 / 620
= 8
Step3:
LCM(4, 215) = 860
GCD(4, 215) = ( 4 x 215 ) / 860
= 4 / 215
= 4
So, Greatest Common Divisor of 512, 120, 620, 215 is 1
