Given numbers are 716,440,690,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 716,440,690,618 is 559747320.
Find LCM of 716,440,690,618 with Prime Factorization
| 2 | 716, 440, 690, 618 |
| 2 | 358, 220, 345, 309 |
| 3 | 179, 110, 345, 309 |
| 5 | 179, 110, 115, 103 |
| 179, 22, 23, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 179 x 22 x 23 x 103 = 559747320
Therefore, the lowest common multiple of 716,440,690,618 is 559747320.
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.
716 x 440 x 690 x 618 = 134339356800
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.
716 : 1, 2, 4, 179, 358, 716
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
618 : 1, 2, 3, 6, 103, 206, 309, 618
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 716,440,690,618, is 2.
Now, the common factors can be found like this.
716:2x 2x 179
440:2x 2x 2x 5x 11
690:2x 3x 5x 23
618:2x 3x 103
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 134339356800/(2x120)
LCM = 134339356800/240
LCM = 559747320
Thus, we can understand that the LCM of 716,440,690,618 is 559747320.
