Given numbers are 220,740,421,667,370
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,740,421,667,370 is 2285768980.
Find LCM of 220,740,421,667,370 with Prime Factorization
| 2 | 220, 740, 421, 667, 370 |
| 2 | 110, 370, 421, 667, 185 |
| 5 | 55, 185, 421, 667, 185 |
| 37 | 11, 37, 421, 667, 37 |
| 11, 1, 421, 667, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 37 x 11 x 1 x 421 x 667 x 1 = 2285768980
Therefore, the lowest common multiple of 220,740,421,667,370 is 2285768980.
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.
220 x 740 x 421 x 667 x 370 = 16914690452000
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
421 : 1, 421
667 : 1, 23, 29, 667
370 : 1, 2, 5, 10, 37, 74, 185, 370
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,740,421,667,370, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
740:2x 2x 5x 37
421:421
667:23x 29
370:2x 5x 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 5x 5x 37 = 7400
Therefore, the value for common factors is 7400.
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 = 16914690452000/(1x7400)
LCM = 16914690452000/7400
LCM = 2285768980
Thus, we can understand that the LCM of 220,740,421,667,370 is 2285768980.
