Given numbers are 955,420,901,865,791
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 955,420,901,865,791 is 1412966922780.
Find LCM of 955,420,901,865,791 with Prime Factorization
| 5 | 955, 420, 901, 865, 791 |
| 7 | 191, 84, 901, 173, 791 |
| 191, 12, 901, 173, 113 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 191 x 12 x 901 x 173 x 113 = 1412966922780
Therefore, the lowest common multiple of 955,420,901,865,791 is 1412966922780.
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.
955 x 420 x 901 x 865 x 791 = 247269211486500
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.
955 : 1, 5, 191, 955
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
901 : 1, 17, 53, 901
865 : 1, 5, 173, 865
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 955,420,901,865,791, is 1.
Now, the common factors can be found like this.
955:5x 191
420:2x 2x 3x 5x 7
901:17x 53
865:5x 173
791:7x 113
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 = 247269211486500/(1x175)
LCM = 247269211486500/175
LCM = 1412966922780
Thus, we can understand that the LCM of 955,420,901,865,791 is 1412966922780.
