Given numbers are 434,870,991,754
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 434,870,991,754 is 2432181570.
Find LCM of 434,870,991,754 with Prime Factorization
| 2 | 434, 870, 991, 754 |
| 29 | 217, 435, 991, 377 |
| 217, 15, 991, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 217 x 15 x 991 x 13 = 2432181570
Therefore, the lowest common multiple of 434,870,991,754 is 2432181570.
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.
434 x 870 x 991 x 754 = 282133062120
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.
434 : 1, 2, 7, 14, 31, 62, 217, 434
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
991 : 1, 991
754 : 1, 2, 13, 26, 29, 58, 377, 754
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 434,870,991,754, is 1.
Now, the common factors can be found like this.
434:2x 7x 31
870:2x 3x 5x 29
991:991
754:2x 13x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 29 = 116
Therefore, the value for common factors is 116.
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 = 282133062120/(1x116)
LCM = 282133062120/116
LCM = 2432181570
Thus, we can understand that the LCM of 434,870,991,754 is 2432181570.
