Given numbers are 827, 634, 186, 645

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

Apply this formula for all numbers.

Step1:

LCM(827, 634) = 524318

GCD(827, 634) = ( 827 x 634 ) / 524318

= 827 / 634

= 827

Step2:

LCM(1, 186) = 186

GCD(1, 186) = ( 1 x 186 ) / 186

= 1 / 186

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 827, 634, 186, 645 is 1
