Given numbers are 978,581,973,429
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,581,973,429 is 11294469186.
Find LCM of 978,581,973,429 with Prime Factorization
3 | 978, 581, 973, 429 |
7 | 326, 581, 973, 143 |
326, 83, 139, 143 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 326 x 83 x 139 x 143 = 11294469186
Therefore, the lowest common multiple of 978,581,973,429 is 11294469186.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
978 x 581 x 973 x 429 = 237183852906
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
978 : 1, 2, 3, 6, 163, 326, 489, 978
581 : 1, 7, 83, 581
973 : 1, 7, 139, 973
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,581,973,429, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
581:7x 83
973:7x 139
429:3x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 237183852906/(1x21)
LCM = 237183852906/21
LCM = 11294469186
Thus, we can understand that the LCM of 978,581,973,429 is 11294469186.
