Given numbers are 251, 189, 491, 597
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(251, 189) = 47439
GCD(251, 189) = ( 251 x 189 ) / 47439
= 251 / 189
= 251
Step2:
LCM(1, 491) = 491
GCD(1, 491) = ( 1 x 491 ) / 491
= 1 / 491
= 1
Step3:
LCM(1, 597) = 597
GCD(1, 597) = ( 1 x 597 ) / 597
= 1 / 597
= 1
So, Greatest Common Divisor of 251, 189, 491, 597 is 1
