Find LCM of 157,561,761,273,539 with Prime Factorization
| 3 | 157, 561, 761, 273, 539 |
| 7 | 157, 187, 761, 91, 539 |
| 11 | 157, 187, 761, 13, 77 |
| 157, 17, 761, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 157 x 17 x 761 x 13 x 7 = 42695942289
Therefore, the lowest common multiple of 157,561,761,273,539 is 42695942289.
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.
157 x 561 x 761 x 273 x 539 = 9862762668759
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.
157 : 1, 157
561 : 1, 3, 11, 17, 33, 51, 187, 561
761 : 1, 761
273 : 1, 3, 7, 13, 21, 39, 91, 273
539 : 1, 7, 11, 49, 77, 539
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,561,761,273,539, is 1.
Now, the common factors can be found like this.
157:157
561:3x 11x 17
761:761
273:3x 7x 13
539:7x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 11 = 231
Therefore, the value for common factors is 231.
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 = 9862762668759/(1x231)
LCM = 9862762668759/231
LCM = 42695942289
Thus, we can understand that the LCM of 157,561,761,273,539 is 42695942289.
