GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(315, 861) = 12915
GCD(315, 861) = ( 315 x 861 ) / 12915
= 315 / 861
= 315
Step2:
LCM(21, 571) = 11991
GCD(21, 571) = ( 21 x 571 ) / 11991
= 21 / 571
= 21
Step3:
LCM(1, 225) = 225
GCD(1, 225) = ( 1 x 225 ) / 225
= 1 / 225
= 1
So, Greatest Common Divisor of 315, 861, 571, 225 is 1
