Given numbers are 782,637,791,896
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,637,791,896 is 3602505088.
Find LCM of 782,637,791,896 with Prime Factorization
| 2 | 782, 637, 791, 896 |
| 7 | 391, 637, 791, 448 |
| 391, 91, 113, 64 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 391 x 91 x 113 x 64 = 3602505088
Therefore, the lowest common multiple of 782,637,791,896 is 3602505088.
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.
782 x 637 x 791 x 896 = 353045498624
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
637 : 1, 7, 13, 49, 91, 637
791 : 1, 7, 113, 791
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,637,791,896, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
637:7x 7x 13
791:7x 113
896:2x 2x 2x 2x 2x 2x 2x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7 = 98
Therefore, the value for common factors is 98.
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 = 353045498624/(1x98)
LCM = 353045498624/98
LCM = 3602505088
Thus, we can understand that the LCM of 782,637,791,896 is 3602505088.
