Given numbers are 420,875,610,444
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,875,610,444 is 23698500.
Find LCM of 420,875,610,444 with Prime Factorization
| 2 | 420, 875, 610, 444 |
| 2 | 210, 875, 305, 222 |
| 3 | 105, 875, 305, 111 |
| 5 | 35, 875, 305, 37 |
| 7 | 7, 175, 61, 37 |
| 1, 25, 61, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 1 x 25 x 61 x 37 = 23698500
Therefore, the lowest common multiple of 420,875,610,444 is 23698500.
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.
420 x 875 x 610 x 444 = 99533700000
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.
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
875 : 1, 5, 7, 25, 35, 125, 175, 875
610 : 1, 2, 5, 10, 61, 122, 305, 610
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,875,610,444, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
875:5x 5x 5x 7
610:2x 5x 61
444:2x 2x 3x 37
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 3x 5x 5x 7 = 4200
Therefore, the value for common factors is 4200.
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 = 99533700000/(1x4200)
LCM = 99533700000/4200
LCM = 23698500
Thus, we can understand that the LCM of 420,875,610,444 is 23698500.
