Given numbers are 700,699,570,422,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 700,699,570,422,870 is 56886507300.
Find LCM of 700,699,570,422,870 with Prime Factorization
| 2 | 700, 699, 570, 422, 870 |
| 3 | 350, 699, 285, 211, 435 |
| 5 | 350, 233, 95, 211, 145 |
| 70, 233, 19, 211, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 70 x 233 x 19 x 211 x 29 = 56886507300
Therefore, the lowest common multiple of 700,699,570,422,870 is 56886507300.
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.
700 x 699 x 570 x 422 x 870 = 102395713140000
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.
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
699 : 1, 3, 233, 699
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
422 : 1, 2, 211, 422
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 700,699,570,422,870, is 1.
Now, the common factors can be found like this.
700:2x 2x 5x 5x 7
699:3x 233
570:2x 3x 5x 19
422:2x 211
870:2x 3x 5x 29
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 2x 3x 3x 5x 5 = 1800
Therefore, the value for common factors is 1800.
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 = 102395713140000/(1x1800)
LCM = 102395713140000/1800
LCM = 56886507300
Thus, we can understand that the LCM of 700,699,570,422,870 is 56886507300.
