Given numbers are 868, 140, 855, 300
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(868, 140) = 4340
GCD(868, 140) = ( 868 x 140 ) / 4340
= 868 / 140
= 868
Step2:
LCM(28, 855) = 23940
GCD(28, 855) = ( 28 x 855 ) / 23940
= 28 / 855
= 28
Step3:
LCM(1, 300) = 300
GCD(1, 300) = ( 1 x 300 ) / 300
= 1 / 300
= 1
So, Greatest Common Divisor of 868, 140, 855, 300 is 1
