Given numbers are 651,947,806,767
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 651,947,806,767 is 945706398.
Find LCM of 651,947,806,767 with Prime Factorization
| 13 | 651, 947, 806, 767 |
| 31 | 651, 947, 62, 59 |
| 21, 947, 2, 59 |
Multiply the prime numbers at the bottom and the left side.
13 x 31 x 21 x 947 x 2 x 59 = 945706398
Therefore, the lowest common multiple of 651,947,806,767 is 945706398.
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.
651 x 947 x 806 x 767 = 381119678394
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.
651 : 1, 3, 7, 21, 31, 93, 217, 651
947 : 1, 947
806 : 1, 2, 13, 26, 31, 62, 403, 806
767 : 1, 13, 59, 767
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,947,806,767, is 1.
Now, the common factors can be found like this.
651:3x 7x 31
947:947
806:2x 13x 31
767:13x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 31 = 403
Therefore, the value for common factors is 403.
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 = 381119678394/(1x403)
LCM = 381119678394/403
LCM = 945706398
Thus, we can understand that the LCM of 651,947,806,767 is 945706398.
