Given numbers are 220, 700, 238, 765
The list of prime factors of all numbers are
Prime factors of 220 are 2 x 2 x 5 x 11
Prime factors of 700 are 2 x 2 x 5 x 5 x 7
Prime factors of 238 are 2 x 7 x 17
Prime factors of 765 are 3 x 3 x 5 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 220, 700, 238, 765
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 700) = 7700
GCD(220, 700) = ( 220 x 700 ) / 7700
= 220 / 700
= 220
Step2:
LCM(20, 238) = 2380
GCD(20, 238) = ( 20 x 238 ) / 2380
= 20 / 238
= 20
Step3:
LCM(2, 765) = 1530
GCD(2, 765) = ( 2 x 765 ) / 1530
= 2 / 765
= 2
So, Greatest Common Divisor of 220, 700, 238, 765 is 1
