Given numbers are 213, 630, 626, 905
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 630) = 44730
GCD(213, 630) = ( 213 x 630 ) / 44730
= 213 / 630
= 213
Step2:
LCM(3, 626) = 1878
GCD(3, 626) = ( 3 x 626 ) / 1878
= 3 / 626
= 3
Step3:
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
= 1 / 905
= 1
So, Greatest Common Divisor of 213, 630, 626, 905 is 1
