Given numbers are 387, 190, 436, 817
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 190) = 73530
GCD(387, 190) = ( 387 x 190 ) / 73530
= 387 / 190
= 387
Step2:
LCM(1, 436) = 436
GCD(1, 436) = ( 1 x 436 ) / 436
= 1 / 436
= 1
Step3:
LCM(1, 817) = 817
GCD(1, 817) = ( 1 x 817 ) / 817
= 1 / 817
= 1
So, Greatest Common Divisor of 387, 190, 436, 817 is 1
