GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 513) = 402192
GCD(784, 513) = ( 784 x 513 ) / 402192
= 784 / 513
= 784
Step2:
LCM(1, 189) = 189
GCD(1, 189) = ( 1 x 189 ) / 189
= 1 / 189
= 1
Step3:
LCM(1, 694) = 694
GCD(1, 694) = ( 1 x 694 ) / 694
= 1 / 694
= 1
So, Greatest Common Divisor of 784, 513, 189, 694 is 1
