Given numbers are 556,155,930,434,974
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,155,930,434,974 is 881362860.
Find LCM of 556,155,930,434,974 with Prime Factorization
| 2 | 556, 155, 930, 434, 974 |
| 5 | 278, 155, 465, 217, 487 |
| 31 | 278, 31, 93, 217, 487 |
| 278, 1, 3, 7, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 31 x 278 x 1 x 3 x 7 x 487 = 881362860
Therefore, the lowest common multiple of 556,155,930,434,974 is 881362860.
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.
556 x 155 x 930 x 434 x 974 = 33879588338400
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.
556 : 1, 2, 4, 139, 278, 556
155 : 1, 5, 31, 155
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
434 : 1, 2, 7, 14, 31, 62, 217, 434
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,155,930,434,974, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
155:5x 31
930:2x 3x 5x 31
434:2x 7x 31
974:2x 487
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 2x 5x 31x 31 = 38440
Therefore, the value for common factors is 38440.
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 = 33879588338400/(1x38440)
LCM = 33879588338400/38440
LCM = 881362860
Thus, we can understand that the LCM of 556,155,930,434,974 is 881362860.
