Find LCM of 665,984,698,615,761 with Prime Factorization
| 2 | 665, 984, 698, 615, 761 |
| 3 | 665, 492, 349, 615, 761 |
| 5 | 665, 164, 349, 205, 761 |
| 41 | 133, 164, 349, 41, 761 |
| 133, 4, 349, 1, 761 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 41 x 133 x 4 x 349 x 1 x 761 = 173790818040
Therefore, the lowest common multiple of 665,984,698,615,761 is 173790818040.
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.
665 x 984 x 698 x 615 x 761 = 213762706189200
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
698 : 1, 2, 349, 698
615 : 1, 3, 5, 15, 41, 123, 205, 615
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,984,698,615,761, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
984:2x 2x 2x 3x 41
698:2x 349
615:3x 5x 41
761:761
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 41 = 1230
Therefore, the value for common factors is 1230.
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 = 213762706189200/(1x1230)
LCM = 213762706189200/1230
LCM = 173790818040
Thus, we can understand that the LCM of 665,984,698,615,761 is 173790818040.
