Given numbers are 665,707,435,508,395
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,707,435,508,395 is 234505522860.
Find LCM of 665,707,435,508,395 with Prime Factorization
| 5 | 665, 707, 435, 508, 395 |
| 7 | 133, 707, 87, 508, 79 |
| 19, 101, 87, 508, 79 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 19 x 101 x 87 x 508 x 79 = 234505522860
Therefore, the lowest common multiple of 665,707,435,508,395 is 234505522860.
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.
665 x 707 x 435 x 508 x 395 = 41038466500500
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
707 : 1, 7, 101, 707
435 : 1, 3, 5, 15, 29, 87, 145, 435
508 : 1, 2, 4, 127, 254, 508
395 : 1, 5, 79, 395
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,707,435,508,395, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
707:7x 101
435:3x 5x 29
508:2x 2x 127
395:5x 79
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 = 41038466500500/(1x175)
LCM = 41038466500500/175
LCM = 234505522860
Thus, we can understand that the LCM of 665,707,435,508,395 is 234505522860.
