Find LCM of 180,748,975,671,478 with Prime Factorization
2 | 180, 748, 975, 671, 478 |
2 | 90, 374, 975, 671, 239 |
3 | 45, 187, 975, 671, 239 |
5 | 15, 187, 325, 671, 239 |
11 | 3, 187, 65, 671, 239 |
3, 17, 65, 61, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 3 x 17 x 65 x 61 x 239 = 31897394100
Therefore, the lowest common multiple of 180,748,975,671,478 is 31897394100.
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.
180 x 748 x 975 x 671 x 478 = 42104560212000
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.
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
671 : 1, 11, 61, 671
478 : 1, 2, 239, 478
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,748,975,671,478, is 1.
Now, the common factors can be found like this.
180:2x 2x 3x 3x 5
748:2x 2x 11x 17
975:3x 5x 5x 13
671:11x 61
478:2x 239
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 2x 3x 5x 11 = 1320
Therefore, the value for common factors is 1320.
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 = 42104560212000/(1x1320)
LCM = 42104560212000/1320
LCM = 31897394100
Thus, we can understand that the LCM of 180,748,975,671,478 is 31897394100.
