Given numbers are 345, 428, 399, 151
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(345, 428) = 147660
GCD(345, 428) = ( 345 x 428 ) / 147660
= 345 / 428
= 345
Step2:
LCM(1, 399) = 399
GCD(1, 399) = ( 1 x 399 ) / 399
= 1 / 399
= 1
Step3:
LCM(1, 151) = 151
GCD(1, 151) = ( 1 x 151 ) / 151
= 1 / 151
= 1
So, Greatest Common Divisor of 345, 428, 399, 151 is 1
