Given numbers are 737,994,785,21
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 737,994,785,21 is 1725221190.
Find LCM of 737,994,785,21 with Prime Factorization
| 7 | 737, 994, 785, 21 |
| 737, 142, 785, 3 |
Multiply the prime numbers at the bottom and the left side.
7 x 737 x 142 x 785 x 3 = 1725221190
Therefore, the lowest common multiple of 737,994,785,21 is 1725221190.
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.
737 x 994 x 785 x 21 = 12076548330
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.
737 : 1, 11, 67, 737
994 : 1, 2, 7, 14, 71, 142, 497, 994
785 : 1, 5, 157, 785
21 : 1, 3, 7, 21
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 737,994,785,21, is 1.
Now, the common factors can be found like this.
737:11x 67
994:2x 7x 71
785:5x 157
21:3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 12076548330/(1x7)
LCM = 12076548330/7
LCM = 1725221190
Thus, we can understand that the LCM of 737,994,785,21 is 1725221190.
