Given numbers are 740, 530, 640, 805

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

Apply this formula for all numbers.

Step1:

LCM(740, 530) = 39220

GCD(740, 530) = ( 740 x 530 ) / 39220

= 740 / 530

= 740

Step2:

LCM(10, 640) = 640

GCD(10, 640) = ( 10 x 640 ) / 640

= 10 / 640

= 10

Step3:

LCM(10, 805) = 1610

GCD(10, 805) = ( 10 x 805 ) / 1610

= 10 / 805

= 10

So, Greatest Common Divisor of 740, 530, 640, 805 is 5
