Given numbers are 555, 311, 785, 868
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(555, 311) = 172605
GCD(555, 311) = ( 555 x 311 ) / 172605
= 555 / 311
= 555
Step2:
LCM(1, 785) = 785
GCD(1, 785) = ( 1 x 785 ) / 785
= 1 / 785
= 1
Step3:
LCM(1, 868) = 868
GCD(1, 868) = ( 1 x 868 ) / 868
= 1 / 868
= 1
So, Greatest Common Divisor of 555, 311, 785, 868 is 1
