Given numbers are 391, 503, 247, 718
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 503) = 196673
GCD(391, 503) = ( 391 x 503 ) / 196673
= 391 / 503
= 391
Step2:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
Step3:
LCM(1, 718) = 718
GCD(1, 718) = ( 1 x 718 ) / 718
= 1 / 718
= 1
So, Greatest Common Divisor of 391, 503, 247, 718 is 1
