Given numbers are 491, 145, 502, 558
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 145) = 71195
GCD(491, 145) = ( 491 x 145 ) / 71195
= 491 / 145
= 491
Step2:
LCM(1, 502) = 502
GCD(1, 502) = ( 1 x 502 ) / 502
= 1 / 502
= 1
Step3:
LCM(1, 558) = 558
GCD(1, 558) = ( 1 x 558 ) / 558
= 1 / 558
= 1
So, Greatest Common Divisor of 491, 145, 502, 558 is 1
