Given numbers are 258, 478, 406, 797
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(258, 478) = 61662
GCD(258, 478) = ( 258 x 478 ) / 61662
= 258 / 478
= 258
Step2:
LCM(2, 406) = 406
GCD(2, 406) = ( 2 x 406 ) / 406
= 2 / 406
= 2
Step3:
LCM(2, 797) = 1594
GCD(2, 797) = ( 2 x 797 ) / 1594
= 2 / 797
= 2
So, Greatest Common Divisor of 258, 478, 406, 797 is 1
