GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(446, 620) = 138260
GCD(446, 620) = ( 446 x 620 ) / 138260
= 446 / 620
= 446
Step2:
LCM(2, 847) = 1694
GCD(2, 847) = ( 2 x 847 ) / 1694
= 2 / 847
= 2
Step3:
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
= 1 / 392
= 1
So, Greatest Common Divisor of 446, 620, 847, 392 is 1
