Find LCM of 898,534,764,440,690 with Prime Factorization
| 2 | 898, 534, 764, 440, 690 |
| 2 | 449, 267, 382, 220, 345 |
| 3 | 449, 267, 191, 110, 345 |
| 5 | 449, 89, 191, 110, 115 |
| 449, 89, 191, 22, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 449 x 89 x 191 x 22 x 23 = 231724248360
Therefore, the lowest common multiple of 898,534,764,440,690 is 231724248360.
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.
898 x 534 x 764 x 440 x 690 = 111227639212800
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.
898 : 1, 2, 449, 898
534 : 1, 2, 3, 6, 89, 178, 267, 534
764 : 1, 2, 4, 191, 382, 764
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
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 898,534,764,440,690, is 2.
Now, the common factors can be found like this.
898:2x 449
534:2x 3x 89
764:2x 2x 191
440:2x 2x 2x 5x 11
690:2x 3x 5x 23
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 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 111227639212800/(2x240)
LCM = 111227639212800/480
LCM = 231724248360
Thus, we can understand that the LCM of 898,534,764,440,690 is 231724248360.
