Given numbers are 355, 200, 858, 387
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(355, 200) = 14200
GCD(355, 200) = ( 355 x 200 ) / 14200
= 355 / 200
= 355
Step2:
LCM(5, 858) = 4290
GCD(5, 858) = ( 5 x 858 ) / 4290
= 5 / 858
= 5
Step3:
LCM(1, 387) = 387
GCD(1, 387) = ( 1 x 387 ) / 387
= 1 / 387
= 1
So, Greatest Common Divisor of 355, 200, 858, 387 is 1
