GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 855) = 60705
GCD(213, 855) = ( 213 x 855 ) / 60705
= 213 / 855
= 213
Step2:
LCM(3, 658) = 1974
GCD(3, 658) = ( 3 x 658 ) / 1974
= 3 / 658
= 3
Step3:
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
= 1 / 813
= 1
So, Greatest Common Divisor of 213, 855, 658, 813 is 1
