Given numbers are 620,838,788,697
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,838,788,697 is 35670132020.
Find LCM of 620,838,788,697 with Prime Factorization
| 2 | 620, 838, 788, 697 |
| 2 | 310, 419, 394, 697 |
| 155, 419, 197, 697 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 155 x 419 x 197 x 697 = 35670132020
Therefore, the lowest common multiple of 620,838,788,697 is 35670132020.
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.
620 x 838 x 788 x 697 = 285361056160
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
838 : 1, 2, 419, 838
788 : 1, 2, 4, 197, 394, 788
697 : 1, 17, 41, 697
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,838,788,697, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
838:2x 419
788:2x 2x 197
697:17x 41
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 2 = 8
Therefore, the value for common factors is 8.
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 = 285361056160/(1x8)
LCM = 285361056160/8
LCM = 35670132020
Thus, we can understand that the LCM of 620,838,788,697 is 35670132020.
