Given numbers are 763, 602, 821, 390

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

Apply this formula for all numbers.

Step1:

LCM(763, 602) = 65618

GCD(763, 602) = ( 763 x 602 ) / 65618

= 763 / 602

= 763

Step2:

LCM(7, 821) = 5747

GCD(7, 821) = ( 7 x 821 ) / 5747

= 7 / 821

= 7

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 763, 602, 821, 390 is 1
