Given numbers are 947, 205, 775, 644

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

Apply this formula for all numbers.

Step1:

LCM(947, 205) = 194135

GCD(947, 205) = ( 947 x 205 ) / 194135

= 947 / 205

= 947

Step2:

LCM(1, 775) = 775

GCD(1, 775) = ( 1 x 775 ) / 775

= 1 / 775

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 947, 205, 775, 644 is 1
