Find LCM of 638,957,697,234,378 with Prime Factorization
2 | 638, 957, 697, 234, 378 |
3 | 319, 957, 697, 117, 189 |
3 | 319, 319, 697, 39, 63 |
11 | 319, 319, 697, 13, 21 |
29 | 29, 29, 697, 13, 21 |
1, 1, 697, 13, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 29 x 1 x 1 x 697 x 13 x 21 = 1092593502
Therefore, the lowest common multiple of 638,957,697,234,378 is 1092593502.
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.
638 x 957 x 697 x 234 x 378 = 37642031330904
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
957 : 1, 3, 11, 29, 33, 87, 319, 957
697 : 1, 17, 41, 697
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,957,697,234,378, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
957:3x 11x 29
697:17x 41
234:2x 3x 3x 13
378:2x 3x 3x 3x 7
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 3x 3x 3x 11x 29 = 34452
Therefore, the value for common factors is 34452.
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 = 37642031330904/(1x34452)
LCM = 37642031330904/34452
LCM = 1092593502
Thus, we can understand that the LCM of 638,957,697,234,378 is 1092593502.
