GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 665) = 141645
GCD(213, 665) = ( 213 x 665 ) / 141645
= 213 / 665
= 213
Step2:
LCM(1, 883) = 883
GCD(1, 883) = ( 1 x 883 ) / 883
= 1 / 883
= 1
Step3:
LCM(1, 810) = 810
GCD(1, 810) = ( 1 x 810 ) / 810
= 1 / 810
= 1
So, Greatest Common Divisor of 213, 665, 883, 810 is 1
