Given numbers are 972, 513, 67, 815

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

Apply this formula for all numbers.

Step1:

LCM(972, 513) = 18468

GCD(972, 513) = ( 972 x 513 ) / 18468

= 972 / 513

= 972

Step2:

LCM(27, 67) = 1809

GCD(27, 67) = ( 27 x 67 ) / 1809

= 27 / 67

= 27

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 972, 513, 67, 815 is 1
