Given numbers are 247, 661, 514, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 661) = 163267
GCD(247, 661) = ( 247 x 661 ) / 163267
= 247 / 661
= 247
Step2:
LCM(1, 514) = 514
GCD(1, 514) = ( 1 x 514 ) / 514
= 1 / 514
= 1
Step3:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
So, Greatest Common Divisor of 247, 661, 514, 991 is 1
