Find LCM of 140,565,556,147,105 with Prime Factorization
| 2 | 140, 565, 556, 147, 105 |
| 2 | 70, 565, 278, 147, 105 |
| 3 | 35, 565, 139, 147, 105 |
| 5 | 35, 565, 139, 49, 35 |
| 7 | 7, 113, 139, 49, 7 |
| 1, 113, 139, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 1 x 113 x 139 x 1 x 7 = 46178580
Therefore, the lowest common multiple of 140,565,556,147,105 is 46178580.
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.
140 x 565 x 556 x 147 x 105 = 678825126000
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
565 : 1, 5, 113, 565
556 : 1, 2, 4, 139, 278, 556
147 : 1, 3, 7, 21, 49, 147
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,565,556,147,105, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
565:5x 113
556:2x 2x 139
147:3x 7x 7
105:3x 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 2x 3x 5x 5x 7x 7 = 14700
Therefore, the value for common factors is 14700.
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 = 678825126000/(1x14700)
LCM = 678825126000/14700
LCM = 46178580
Thus, we can understand that the LCM of 140,565,556,147,105 is 46178580.
