GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 290) = 49590
GCD(855, 290) = ( 855 x 290 ) / 49590
= 855 / 290
= 855
Step2:
LCM(5, 153) = 765
GCD(5, 153) = ( 5 x 153 ) / 765
= 5 / 153
= 5
Step3:
LCM(1, 387) = 387
GCD(1, 387) = ( 1 x 387 ) / 387
= 1 / 387
= 1
So, Greatest Common Divisor of 855, 290, 153, 387 is 1
