Given numbers are 212,671,610,785,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 212,671,610,785,945 is 21105217980.
Find LCM of 212,671,610,785,945 with Prime Factorization
| 2 | 212, 671, 610, 785, 945 |
| 5 | 106, 671, 305, 785, 945 |
| 61 | 106, 671, 61, 157, 189 |
| 106, 11, 1, 157, 189 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 61 x 106 x 11 x 1 x 157 x 189 = 21105217980
Therefore, the lowest common multiple of 212,671,610,785,945 is 21105217980.
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.
212 x 671 x 610 x 785 x 945 = 64370914839000
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.
212 : 1, 2, 4, 53, 106, 212
671 : 1, 11, 61, 671
610 : 1, 2, 5, 10, 61, 122, 305, 610
785 : 1, 5, 157, 785
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,671,610,785,945, is 1.
Now, the common factors can be found like this.
212:2x 2x 53
671:11x 61
610:2x 5x 61
785:5x 157
945:3x 3x 3x 5x 7
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 5x 61 = 3050
Therefore, the value for common factors is 3050.
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 = 64370914839000/(1x3050)
LCM = 64370914839000/3050
LCM = 21105217980
Thus, we can understand that the LCM of 212,671,610,785,945 is 21105217980.
