Given numbers are 390, 513, 758, 258
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 513) = 66690
GCD(390, 513) = ( 390 x 513 ) / 66690
= 390 / 513
= 390
Step2:
LCM(3, 758) = 2274
GCD(3, 758) = ( 3 x 758 ) / 2274
= 3 / 758
= 3
Step3:
LCM(1, 258) = 258
GCD(1, 258) = ( 1 x 258 ) / 258
= 1 / 258
= 1
So, Greatest Common Divisor of 390, 513, 758, 258 is 1
