GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(605, 855) = 103455
GCD(605, 855) = ( 605 x 855 ) / 103455
= 605 / 855
= 605
Step2:
LCM(5, 783) = 3915
GCD(5, 783) = ( 5 x 783 ) / 3915
= 5 / 783
= 5
Step3:
LCM(1, 187) = 187
GCD(1, 187) = ( 1 x 187 ) / 187
= 1 / 187
= 1
So, Greatest Common Divisor of 605, 855, 783, 187 is 1
