GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 189) = 21168
GCD(784, 189) = ( 784 x 189 ) / 21168
= 784 / 189
= 784
Step2:
LCM(7, 139) = 973
GCD(7, 139) = ( 7 x 139 ) / 973
= 7 / 139
= 7
Step3:
LCM(1, 842) = 842
GCD(1, 842) = ( 1 x 842 ) / 842
= 1 / 842
= 1
So, Greatest Common Divisor of 784, 189, 139, 842 is 1
