Given numbers are 681, 400, 515, 546
The list of prime factors of all numbers are
Prime factors of 681 are 3 x 227
Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5
Prime factors of 515 are 5 x 103
Prime factors of 546 are 2 x 3 x 7 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 681, 400, 515, 546
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(681, 400) = 272400
GCD(681, 400) = ( 681 x 400 ) / 272400
= 681 / 400
= 681
Step2:
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
= 1 / 515
= 1
Step3:
LCM(1, 546) = 546
GCD(1, 546) = ( 1 x 546 ) / 546
= 1 / 546
= 1
So, Greatest Common Divisor of 681, 400, 515, 546 is 1
