Given numbers are 123, 568, 540, 728
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 568) = 69864
GCD(123, 568) = ( 123 x 568 ) / 69864
= 123 / 568
= 123
Step2:
LCM(1, 540) = 540
GCD(1, 540) = ( 1 x 540 ) / 540
= 1 / 540
= 1
Step3:
LCM(1, 728) = 728
GCD(1, 728) = ( 1 x 728 ) / 728
= 1 / 728
= 1
So, Greatest Common Divisor of 123, 568, 540, 728 is 1
