Given numbers are 702,694,624,381
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 702,694,624,381 is 247491504.
Find LCM of 702,694,624,381 with Prime Factorization
| 2 | 702, 694, 624, 381 |
| 3 | 351, 347, 312, 381 |
| 13 | 117, 347, 104, 127 |
| 9, 347, 8, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 9 x 347 x 8 x 127 = 247491504
Therefore, the lowest common multiple of 702,694,624,381 is 247491504.
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.
702 x 694 x 624 x 381 = 115826023872
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.
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
694 : 1, 2, 347, 694
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
381 : 1, 3, 127, 381
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,694,624,381, is 1.
Now, the common factors can be found like this.
702:2x 3x 3x 3x 13
694:2x 347
624:2x 2x 2x 2x 3x 13
381:3x 127
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 13 = 468
Therefore, the value for common factors is 468.
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 = 115826023872/(1x468)
LCM = 115826023872/468
LCM = 247491504
Thus, we can understand that the LCM of 702,694,624,381 is 247491504.
