GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(392, 329) = 18424
GCD(392, 329) = ( 392 x 329 ) / 18424
= 392 / 329
= 392
Step2:
LCM(7, 824) = 5768
GCD(7, 824) = ( 7 x 824 ) / 5768
= 7 / 824
= 7
Step3:
LCM(1, 784) = 784
GCD(1, 784) = ( 1 x 784 ) / 784
= 1 / 784
= 1
So, Greatest Common Divisor of 392, 329, 824, 784 is 1
