Given numbers are 491, 581, 261, 137
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 581) = 285271
GCD(491, 581) = ( 491 x 581 ) / 285271
= 491 / 581
= 491
Step2:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
Step3:
LCM(1, 137) = 137
GCD(1, 137) = ( 1 x 137 ) / 137
= 1 / 137
= 1
So, Greatest Common Divisor of 491, 581, 261, 137 is 1
