Given numbers are 856, 105, 127, 644

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

Apply this formula for all numbers.

Step1:

LCM(856, 105) = 89880

GCD(856, 105) = ( 856 x 105 ) / 89880

= 856 / 105

= 856

Step2:

LCM(1, 127) = 127

GCD(1, 127) = ( 1 x 127 ) / 127

= 1 / 127

= 1

Step3:

LCM(1, 644) = 644

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

= 1 / 644

= 1

So, Greatest Common Divisor of 856, 105, 127, 644 is 1
