The LCM of 887,700,722,665 is 224144900.
Find LCM of 887,700,722,665 with Prime Factorization
| 2 | 887, 700, 722, 665 |
| 5 | 887, 350, 361, 665 |
| 7 | 887, 70, 361, 133 |
| 19 | 887, 10, 361, 19 |
| 887, 10, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 19 x 887 x 10 x 1 x 19 = 224144900
Therefore, the lowest common multiple of 887,700,722,665 is 224144900.
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.
887 x 700 x 722 x 665 = 298112717000
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.
887 : 1, 887
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
722 : 1, 2, 19, 38, 361, 722
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 887,700,722,665, is 1.
Now, the common factors can be found like this.
887:887
700:2x 2x 5x 5x 7
722:2x 19x 19
665:5x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 19 = 1330
Therefore, the value for common factors is 1330.
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 = 298112717000/(1x1330)
LCM = 298112717000/1330
LCM = 224144900
Thus, we can understand that the LCM of 887,700,722,665 is 224144900.
