Given numbers are 868, 104, 645, 538
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(868, 104) = 22568
GCD(868, 104) = ( 868 x 104 ) / 22568
= 868 / 104
= 868
Step2:
LCM(4, 645) = 2580
GCD(4, 645) = ( 4 x 645 ) / 2580
= 4 / 645
= 4
Step3:
LCM(1, 538) = 538
GCD(1, 538) = ( 1 x 538 ) / 538
= 1 / 538
= 1
So, Greatest Common Divisor of 868, 104, 645, 538 is 1
