GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(918, 793) = 727974
GCD(918, 793) = ( 918 x 793 ) / 727974
= 918 / 793
= 918
Step2:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
Step3:
LCM(1, 810) = 810
GCD(1, 810) = ( 1 x 810 ) / 810
= 1 / 810
= 1
So, Greatest Common Divisor of 918, 793, 639, 810 is 1
