Given numbers are 147, 513, 191, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(147, 513) = 25137
GCD(147, 513) = ( 147 x 513 ) / 25137
= 147 / 513
= 147
Step2:
LCM(3, 191) = 573
GCD(3, 191) = ( 3 x 191 ) / 573
= 3 / 191
= 3
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 147, 513, 191, 221 is 1
