Find LCM of 616,440,618,139,691 with Prime Factorization
| 2 | 616, 440, 618, 139, 691 |
| 2 | 308, 220, 309, 139, 691 |
| 2 | 154, 110, 309, 139, 691 |
| 11 | 77, 55, 309, 139, 691 |
| 7, 5, 309, 139, 691 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 7 x 5 x 309 x 139 x 691 = 91411754280
Therefore, the lowest common multiple of 616,440,618,139,691 is 91411754280.
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.
616 x 440 x 618 x 139 x 691 = 16088468753280
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.
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
618 : 1, 2, 3, 6, 103, 206, 309, 618
139 : 1, 139
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 616,440,618,139,691, is 1.
Now, the common factors can be found like this.
616:2x 2x 2x 7x 11
440:2x 2x 2x 5x 11
618:2x 3x 103
139:139
691:691
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 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 16088468753280/(1x176)
LCM = 16088468753280/176
LCM = 91411754280
Thus, we can understand that the LCM of 616,440,618,139,691 is 91411754280.
