Given numbers are 491, 254, 391, 587
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 254) = 124714
GCD(491, 254) = ( 491 x 254 ) / 124714
= 491 / 254
= 491
Step2:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
Step3:
LCM(1, 587) = 587
GCD(1, 587) = ( 1 x 587 ) / 587
= 1 / 587
= 1
So, Greatest Common Divisor of 491, 254, 391, 587 is 1
