Given numbers are 784, 557, 809, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 557) = 436688
GCD(784, 557) = ( 784 x 557 ) / 436688
= 784 / 557
= 784
Step2:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 784, 557, 809, 815 is 1
