Given numbers are 720, 524, 655, 400
The list of prime factors of all numbers are
Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5
Prime factors of 524 are 2 x 2 x 131
Prime factors of 655 are 5 x 131
Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 720, 524, 655, 400
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 524) = 94320
GCD(720, 524) = ( 720 x 524 ) / 94320
= 720 / 524
= 720
Step2:
LCM(4, 655) = 2620
GCD(4, 655) = ( 4 x 655 ) / 2620
= 4 / 655
= 4
Step3:
LCM(1, 400) = 400
GCD(1, 400) = ( 1 x 400 ) / 400
= 1 / 400
= 1
So, Greatest Common Divisor of 720, 524, 655, 400 is 1
