Given numbers are 940,421,770,913
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 940,421,770,913 is 2529174340.
Find LCM of 940,421,770,913 with Prime Factorization
| 2 | 940, 421, 770, 913 |
| 5 | 470, 421, 385, 913 |
| 11 | 94, 421, 77, 913 |
| 94, 421, 7, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 94 x 421 x 7 x 83 = 2529174340
Therefore, the lowest common multiple of 940,421,770,913 is 2529174340.
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.
940 x 421 x 770 x 913 = 278209177400
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.
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
421 : 1, 421
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
913 : 1, 11, 83, 913
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 940,421,770,913, is 1.
Now, the common factors can be found like this.
940:2x 2x 5x 47
421:421
770:2x 5x 7x 11
913:11x 83
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 11 = 110
Therefore, the value for common factors is 110.
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 = 278209177400/(1x110)
LCM = 278209177400/110
LCM = 2529174340
Thus, we can understand that the LCM of 940,421,770,913 is 2529174340.
