Given numbers are 628,594,620,240
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,594,620,240 is 115639920.
Find LCM of 628,594,620,240 with Prime Factorization
| 2 | 628, 594, 620, 240 |
| 2 | 314, 297, 310, 120 |
| 3 | 157, 297, 155, 60 |
| 5 | 157, 99, 155, 20 |
| 157, 99, 31, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 157 x 99 x 31 x 4 = 115639920
Therefore, the lowest common multiple of 628,594,620,240 is 115639920.
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.
628 x 594 x 620 x 240 = 55507161600
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.
628 : 1, 2, 4, 157, 314, 628
594 : 1, 2, 3, 6, 9, 11, 18, 22, 27, 33, 54, 66, 99, 198, 297, 594
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,594,620,240, is 2.
Now, the common factors can be found like this.
628:2x 2x 157
594:2x 3x 3x 3x 11
620:2x 2x 5x 31
240:2x 2x 2x 2x 3x 5
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 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 55507161600/(2x240)
LCM = 55507161600/480
LCM = 115639920
Thus, we can understand that the LCM of 628,594,620,240 is 115639920.
