Given numbers are 525,392,695,865
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 525,392,695,865 is 706981800.
Find LCM of 525,392,695,865 with Prime Factorization
| 5 | 525, 392, 695, 865 |
| 7 | 105, 392, 139, 173 |
| 15, 56, 139, 173 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 15 x 56 x 139 x 173 = 706981800
Therefore, the lowest common multiple of 525,392,695,865 is 706981800.
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.
525 x 392 x 695 x 865 = 123721815000
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.
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
695 : 1, 5, 139, 695
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 525,392,695,865, is 1.
Now, the common factors can be found like this.
525:3x 5x 5x 7
392:2x 2x 2x 7x 7
695:5x 139
865:5x 173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7 = 175
Therefore, the value for common factors is 175.
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 = 123721815000/(1x175)
LCM = 123721815000/175
LCM = 706981800
Thus, we can understand that the LCM of 525,392,695,865 is 706981800.
