Given numbers are 861, 693, 946, 253

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

Apply this formula for all numbers.

Step1:

LCM(861, 693) = 28413

GCD(861, 693) = ( 861 x 693 ) / 28413

= 861 / 693

= 861

Step2:

LCM(21, 946) = 19866

GCD(21, 946) = ( 21 x 946 ) / 19866

= 21 / 946

= 21

Step3:

LCM(1, 253) = 253

GCD(1, 253) = ( 1 x 253 ) / 253

= 1 / 253

= 1

So, Greatest Common Divisor of 861, 693, 946, 253 is 1
