Given numbers are 670,502,308,740
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 670,502,308,740 is 958232660.
Find LCM of 670,502,308,740 with Prime Factorization
| 2 | 670, 502, 308, 740 |
| 2 | 335, 251, 154, 370 |
| 5 | 335, 251, 77, 185 |
| 67, 251, 77, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 67 x 251 x 77 x 37 = 958232660
Therefore, the lowest common multiple of 670,502,308,740 is 958232660.
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.
670 x 502 x 308 x 740 = 76658612800
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.
670 : 1, 2, 5, 10, 67, 134, 335, 670
502 : 1, 2, 251, 502
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,502,308,740, is 2.
Now, the common factors can be found like this.
670:2x 5x 67
502:2x 251
308:2x 2x 7x 11
740:2x 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 5 = 40
Therefore, the value for common factors is 40.
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 = 76658612800/(2x40)
LCM = 76658612800/80
LCM = 958232660
Thus, we can understand that the LCM of 670,502,308,740 is 958232660.
