Given numbers are 698,475,449,980,769
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,475,449,980,769 is 11218835723900.
Find LCM of 698,475,449,980,769 with Prime Factorization
| 2 | 698, 475, 449, 980, 769 |
| 5 | 349, 475, 449, 490, 769 |
| 349, 95, 449, 98, 769 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 349 x 95 x 449 x 98 x 769 = 11218835723900
Therefore, the lowest common multiple of 698,475,449,980,769 is 11218835723900.
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.
698 x 475 x 449 x 980 x 769 = 112188357239000
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.
698 : 1, 2, 349, 698
475 : 1, 5, 19, 25, 95, 475
449 : 1, 449
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
769 : 1, 769
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,475,449,980,769, is 1.
Now, the common factors can be found like this.
698:2x 349
475:5x 5x 19
449:449
980:2x 2x 5x 7x 7
769:769
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 112188357239000/(1x10)
LCM = 112188357239000/10
LCM = 11218835723900
Thus, we can understand that the LCM of 698,475,449,980,769 is 11218835723900.
