Given numbers are 402, 370, 822, 618

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(402, 370) = 74370

GCD(402, 370) = ( 402 x 370 ) / 74370

= 402 / 370

= 402

Step2:

LCM(2, 822) = 822

GCD(2, 822) = ( 2 x 822 ) / 822

= 2 / 822

= 2

Step3:

LCM(2, 618) = 618

GCD(2, 618) = ( 2 x 618 ) / 618

= 2 / 618

= 2

So, Greatest Common Divisor of 402, 370, 822, 618 is 2
