Given numbers are 641, 796, 221, 905
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(641, 796) = 510236
GCD(641, 796) = ( 641 x 796 ) / 510236
= 641 / 796
= 641
Step2:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
Step3:
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
= 1 / 905
= 1
So, Greatest Common Divisor of 641, 796, 221, 905 is 1
