Given numbers are 740,780,223,821,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 740,780,223,821,715 is 58121529180.
Find LCM of 740,780,223,821,715 with Prime Factorization
| 2 | 740, 780, 223, 821, 715 |
| 2 | 370, 390, 223, 821, 715 |
| 5 | 185, 195, 223, 821, 715 |
| 13 | 37, 39, 223, 821, 143 |
| 37, 3, 223, 821, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 37 x 3 x 223 x 821 x 11 = 58121529180
Therefore, the lowest common multiple of 740,780,223,821,715 is 58121529180.
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.
740 x 780 x 223 x 821 x 715 = 75557987934000
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.
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
223 : 1, 223
821 : 1, 821
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 740,780,223,821,715, is 1.
Now, the common factors can be found like this.
740:2x 2x 5x 37
780:2x 2x 3x 5x 13
223:223
821:821
715:5x 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.
2x 2x 5x 5x 13 = 1300
Therefore, the value for common factors is 1300.
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 = 75557987934000/(1x1300)
LCM = 75557987934000/1300
LCM = 58121529180
Thus, we can understand that the LCM of 740,780,223,821,715 is 58121529180.
