Given numbers are 568, 646, 205, 731
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(568, 646) = 183464
GCD(568, 646) = ( 568 x 646 ) / 183464
= 568 / 646
= 568
Step2:
LCM(2, 205) = 410
GCD(2, 205) = ( 2 x 205 ) / 410
= 2 / 205
= 2
Step3:
LCM(1, 731) = 731
GCD(1, 731) = ( 1 x 731 ) / 731
= 1 / 731
= 1
So, Greatest Common Divisor of 568, 646, 205, 731 is 1
