GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 961) = 753424
GCD(784, 961) = ( 784 x 961 ) / 753424
= 784 / 961
= 784
Step2:
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
= 1 / 402
= 1
Step3:
LCM(1, 919) = 919
GCD(1, 919) = ( 1 x 919 ) / 919
= 1 / 919
= 1
So, Greatest Common Divisor of 784, 961, 402, 919 is 1
