Find LCM of 942,785,507,580,638 with Prime Factorization
2 | 942, 785, 507, 580, 638 |
3 | 471, 785, 507, 290, 319 |
5 | 157, 785, 169, 290, 319 |
29 | 157, 157, 169, 58, 319 |
157 | 157, 157, 169, 2, 11 |
1, 1, 169, 2, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 29 x 157 x 1 x 1 x 169 x 2 x 11 = 507841620
Therefore, the lowest common multiple of 942,785,507,580,638 is 507841620.
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.
942 x 785 x 507 x 580 x 638 = 138732173751600
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.
942 : 1, 2, 3, 6, 157, 314, 471, 942
785 : 1, 5, 157, 785
507 : 1, 3, 13, 39, 169, 507
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,785,507,580,638, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
785:5x 157
507:3x 13x 13
580:2x 2x 5x 29
638:2x 11x 29
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 5x 29x 157 = 273180
Therefore, the value for common factors is 273180.
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 = 138732173751600/(1x273180)
LCM = 138732173751600/273180
LCM = 507841620
Thus, we can understand that the LCM of 942,785,507,580,638 is 507841620.
