Given numbers are 186, 312, 509, 821

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

Apply this formula for all numbers.

Step1:

LCM(186, 312) = 9672

GCD(186, 312) = ( 186 x 312 ) / 9672

= 186 / 312

= 186

Step2:

LCM(6, 509) = 3054

GCD(6, 509) = ( 6 x 509 ) / 3054

= 6 / 509

= 6

Step3:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

So, Greatest Common Divisor of 186, 312, 509, 821 is 1
