Given numbers are 395, 515, 994, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(395, 515) = 40685
GCD(395, 515) = ( 395 x 515 ) / 40685
= 395 / 515
= 395
Step2:
LCM(5, 994) = 4970
GCD(5, 994) = ( 5 x 994 ) / 4970
= 5 / 994
= 5
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 395, 515, 994, 221 is 1
