Given numbers are 869, 242, 987, 705

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

Apply this formula for all numbers.

Step1:

LCM(869, 242) = 19118

GCD(869, 242) = ( 869 x 242 ) / 19118

= 869 / 242

= 869

Step2:

LCM(11, 987) = 10857

GCD(11, 987) = ( 11 x 987 ) / 10857

= 11 / 987

= 11

Step3:

LCM(1, 705) = 705

GCD(1, 705) = ( 1 x 705 ) / 705

= 1 / 705

= 1

So, Greatest Common Divisor of 869, 242, 987, 705 is 1
