Given numbers are 515, 841, 230, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 841) = 433115
GCD(515, 841) = ( 515 x 841 ) / 433115
= 515 / 841
= 515
Step2:
LCM(1, 230) = 230
GCD(1, 230) = ( 1 x 230 ) / 230
= 1 / 230
= 1
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 515, 841, 230, 221 is 1
