Given numbers are 697,643,335,218,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 697,643,335,218,938 is 229109496910.
Find LCM of 697,643,335,218,938 with Prime Factorization
| 2 | 697, 643, 335, 218, 938 |
| 67 | 697, 643, 335, 109, 469 |
| 697, 643, 5, 109, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 67 x 697 x 643 x 5 x 109 x 7 = 229109496910
Therefore, the lowest common multiple of 697,643,335,218,938 is 229109496910.
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.
697 x 643 x 335 x 218 x 938 = 30700672585940
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.
697 : 1, 17, 41, 697
643 : 1, 643
335 : 1, 5, 67, 335
218 : 1, 2, 109, 218
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,643,335,218,938, is 1.
Now, the common factors can be found like this.
697:17x 41
643:643
335:5x 67
218:2x 109
938:2x 7x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 67 = 134
Therefore, the value for common factors is 134.
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 = 30700672585940/(1x134)
LCM = 30700672585940/134
LCM = 229109496910
Thus, we can understand that the LCM of 697,643,335,218,938 is 229109496910.
