Given numbers are 578, 634, 813, 791
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(578, 634) = 183226
GCD(578, 634) = ( 578 x 634 ) / 183226
= 578 / 634
= 578
Step2:
LCM(2, 813) = 1626
GCD(2, 813) = ( 2 x 813 ) / 1626
= 2 / 813
= 2
Step3:
LCM(1, 791) = 791
GCD(1, 791) = ( 1 x 791 ) / 791
= 1 / 791
= 1
So, Greatest Common Divisor of 578, 634, 813, 791 is 1
