Given numbers are 210, 763, 140, 805

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

Apply this formula for all numbers.

Step1:

LCM(210, 763) = 22890

GCD(210, 763) = ( 210 x 763 ) / 22890

= 210 / 763

= 210

Step2:

LCM(7, 140) = 140

GCD(7, 140) = ( 7 x 140 ) / 140

= 7 / 140

= 7

Step3:

LCM(7, 805) = 805

GCD(7, 805) = ( 7 x 805 ) / 805

= 7 / 805

= 7

So, Greatest Common Divisor of 210, 763, 140, 805 is 7
