GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(666, 570) = 63270
GCD(666, 570) = ( 666 x 570 ) / 63270
= 666 / 570
= 666
Step2:
LCM(6, 396) = 396
GCD(6, 396) = ( 6 x 396 ) / 396
= 6 / 396
= 6
Step3:
LCM(6, 378) = 378
GCD(6, 378) = ( 6 x 378 ) / 378
= 6 / 378
= 6
So, Greatest Common Divisor of 666, 570, 396, 378 is 6
