Given numbers are 855, 615, 534, 747

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

Apply this formula for all numbers.

Step1:

LCM(855, 615) = 35055

GCD(855, 615) = ( 855 x 615 ) / 35055

= 855 / 615

= 855

Step2:

LCM(15, 534) = 2670

GCD(15, 534) = ( 15 x 534 ) / 2670

= 15 / 534

= 15

Step3:

LCM(3, 747) = 747

GCD(3, 747) = ( 3 x 747 ) / 747

= 3 / 747

= 3

So, Greatest Common Divisor of 855, 615, 534, 747 is 3
