GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(666, 685) = 456210
GCD(666, 685) = ( 666 x 685 ) / 456210
= 666 / 685
= 666
Step2:
LCM(1, 784) = 784
GCD(1, 784) = ( 1 x 784 ) / 784
= 1 / 784
= 1
Step3:
LCM(1, 529) = 529
GCD(1, 529) = ( 1 x 529 ) / 529
= 1 / 529
= 1
So, Greatest Common Divisor of 666, 685, 784, 529 is 1
