Given numbers are 417, 778, 581, 820
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(417, 778) = 324426
GCD(417, 778) = ( 417 x 778 ) / 324426
= 417 / 778
= 417
Step2:
LCM(1, 581) = 581
GCD(1, 581) = ( 1 x 581 ) / 581
= 1 / 581
= 1
Step3:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
So, Greatest Common Divisor of 417, 778, 581, 820 is 1
