Given numbers are 313,735,642,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 313,735,642,140 is 98463540.
Find LCM of 313,735,642,140 with Prime Factorization
2 | 313, 735, 642, 140 |
3 | 313, 735, 321, 70 |
5 | 313, 245, 107, 70 |
7 | 313, 49, 107, 14 |
313, 7, 107, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 313 x 7 x 107 x 2 = 98463540
Therefore, the lowest common multiple of 313,735,642,140 is 98463540.
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.
313 x 735 x 642 x 140 = 20677343400
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.
313 : 1, 313
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
642 : 1, 2, 3, 6, 107, 214, 321, 642
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 313,735,642,140, is 1.
Now, the common factors can be found like this.
313:313
735:3x 5x 7x 7
642:2x 3x 107
140:2x 2x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 20677343400/(1x210)
LCM = 20677343400/210
LCM = 98463540
Thus, we can understand that the LCM of 313,735,642,140 is 98463540.
