Given numbers are 387, 197, 758, 407
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 197) = 76239
GCD(387, 197) = ( 387 x 197 ) / 76239
= 387 / 197
= 387
Step2:
LCM(1, 758) = 758
GCD(1, 758) = ( 1 x 758 ) / 758
= 1 / 758
= 1
Step3:
LCM(1, 407) = 407
GCD(1, 407) = ( 1 x 407 ) / 407
= 1 / 407
= 1
So, Greatest Common Divisor of 387, 197, 758, 407 is 1
