GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(419, 423) = 177237
GCD(419, 423) = ( 419 x 423 ) / 177237
= 419 / 423
= 419
Step2:
LCM(1, 662) = 662
GCD(1, 662) = ( 1 x 662 ) / 662
= 1 / 662
= 1
Step3:
LCM(1, 784) = 784
GCD(1, 784) = ( 1 x 784 ) / 784
= 1 / 784
= 1
So, Greatest Common Divisor of 419, 423, 662, 784 is 1
