GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(457, 717) = 327669
GCD(457, 717) = ( 457 x 717 ) / 327669
= 457 / 717
= 457
Step2:
LCM(1, 47) = 47
GCD(1, 47) = ( 1 x 47 ) / 47
= 1 / 47
= 1
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 457, 717, 47, 781 is 1
