Given numbers are 216, 620, 868, 869
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(216, 620) = 33480
GCD(216, 620) = ( 216 x 620 ) / 33480
= 216 / 620
= 216
Step2:
LCM(4, 868) = 868
GCD(4, 868) = ( 4 x 868 ) / 868
= 4 / 868
= 4
Step3:
LCM(4, 869) = 3476
GCD(4, 869) = ( 4 x 869 ) / 3476
= 4 / 869
= 4
So, Greatest Common Divisor of 216, 620, 868, 869 is 1
