Given numbers are 784,949,802,791,137
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,949,802,791,137 is 4618762790096.
Find LCM of 784,949,802,791,137 with Prime Factorization
| 2 | 784, 949, 802, 791, 137 |
| 7 | 392, 949, 401, 791, 137 |
| 56, 949, 401, 113, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 56 x 949 x 401 x 113 x 137 = 4618762790096
Therefore, the lowest common multiple of 784,949,802,791,137 is 4618762790096.
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.
784 x 949 x 802 x 791 x 137 = 64662679061344
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
949 : 1, 13, 73, 949
802 : 1, 2, 401, 802
791 : 1, 7, 113, 791
137 : 1, 137
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,949,802,791,137, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
949:13x 73
802:2x 401
791:7x 113
137:137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 64662679061344/(1x14)
LCM = 64662679061344/14
LCM = 4618762790096
Thus, we can understand that the LCM of 784,949,802,791,137 is 4618762790096.
