Given numbers are 784, 423, 581, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 423) = 331632
GCD(784, 423) = ( 784 x 423 ) / 331632
= 784 / 423
= 784
Step2:
LCM(1, 581) = 581
GCD(1, 581) = ( 1 x 581 ) / 581
= 1 / 581
= 1
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 784, 423, 581, 809 is 1
