Given numbers are 797, 120, 218, 491
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(797, 120) = 95640
GCD(797, 120) = ( 797 x 120 ) / 95640
= 797 / 120
= 797
Step2:
LCM(1, 218) = 218
GCD(1, 218) = ( 1 x 218 ) / 218
= 1 / 218
= 1
Step3:
LCM(1, 491) = 491
GCD(1, 491) = ( 1 x 491 ) / 491
= 1 / 491
= 1
So, Greatest Common Divisor of 797, 120, 218, 491 is 1
