Given numbers are 172,931,436,950,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 172,931,436,950,782 is 170616642700.
Find LCM of 172,931,436,950,782 with Prime Factorization
| 2 | 172, 931, 436, 950, 782 |
| 2 | 86, 931, 218, 475, 391 |
| 19 | 43, 931, 109, 475, 391 |
| 43, 49, 109, 25, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 43 x 49 x 109 x 25 x 391 = 170616642700
Therefore, the lowest common multiple of 172,931,436,950,782 is 170616642700.
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.
172 x 931 x 436 x 950 x 782 = 51867459380800
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.
172 : 1, 2, 4, 43, 86, 172
931 : 1, 7, 19, 49, 133, 931
436 : 1, 2, 4, 109, 218, 436
950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,931,436,950,782, is 1.
Now, the common factors can be found like this.
172:2x 2x 43
931:7x 7x 19
436:2x 2x 109
950:2x 5x 5x 19
782:2x 17x 23
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 2x 19 = 304
Therefore, the value for common factors is 304.
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 = 51867459380800/(1x304)
LCM = 51867459380800/304
LCM = 170616642700
Thus, we can understand that the LCM of 172,931,436,950,782 is 170616642700.
