Given numbers are 186, 654, 639, 175

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

Apply this formula for all numbers.

Step1:

LCM(186, 654) = 20274

GCD(186, 654) = ( 186 x 654 ) / 20274

= 186 / 654

= 186

Step2:

LCM(6, 639) = 1278

GCD(6, 639) = ( 6 x 639 ) / 1278

= 6 / 639

= 6

Step3:

LCM(3, 175) = 525

GCD(3, 175) = ( 3 x 175 ) / 525

= 3 / 175

= 3

So, Greatest Common Divisor of 186, 654, 639, 175 is 1
