Find LCM of 657,440,798,785,803 with Prime Factorization
2 | 657, 440, 798, 785, 803 |
3 | 657, 220, 399, 785, 803 |
5 | 219, 220, 133, 785, 803 |
11 | 219, 44, 133, 157, 803 |
73 | 219, 4, 133, 157, 73 |
3, 4, 133, 157, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 73 x 3 x 4 x 133 x 157 x 1 = 6036279480
Therefore, the lowest common multiple of 657,440,798,785,803 is 6036279480.
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.
657 x 440 x 798 x 785 x 803 = 145413972673200
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.
657 : 1, 3, 9, 73, 219, 657
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
785 : 1, 5, 157, 785
803 : 1, 11, 73, 803
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,440,798,785,803, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
440:2x 2x 2x 5x 11
798:2x 3x 7x 19
785:5x 157
803:11x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 11x 73 = 24090
Therefore, the value for common factors is 24090.
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 = 145413972673200/(1x24090)
LCM = 145413972673200/24090
LCM = 6036279480
Thus, we can understand that the LCM of 657,440,798,785,803 is 6036279480.
