Given numbers are 787,107,910,700,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 787,107,910,700,931 is 101918152700.
Find LCM of 787,107,910,700,931 with Prime Factorization
| 2 | 787, 107, 910, 700, 931 |
| 5 | 787, 107, 455, 350, 931 |
| 7 | 787, 107, 91, 70, 931 |
| 787, 107, 13, 10, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 787 x 107 x 13 x 10 x 133 = 101918152700
Therefore, the lowest common multiple of 787,107,910,700,931 is 101918152700.
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.
787 x 107 x 910 x 700 x 931 = 49939894823000
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.
787 : 1, 787
107 : 1, 107
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,107,910,700,931, is 1.
Now, the common factors can be found like this.
787:787
107:107
910:2x 5x 7x 13
700:2x 2x 5x 5x 7
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 7 = 490
Therefore, the value for common factors is 490.
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 = 49939894823000/(1x490)
LCM = 49939894823000/490
LCM = 101918152700
Thus, we can understand that the LCM of 787,107,910,700,931 is 101918152700.
