Given numbers are 989,735,956,338,761
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,735,956,338,761 is 89374347540660.
Find LCM of 989,735,956,338,761 with Prime Factorization
| 2 | 989, 735, 956, 338, 761 |
| 989, 735, 478, 169, 761 |
Multiply the prime numbers at the bottom and the left side.
2 x 989 x 735 x 478 x 169 x 761 = 89374347540660
Therefore, the lowest common multiple of 989,735,956,338,761 is 89374347540660.
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.
989 x 735 x 956 x 338 x 761 = 178748695081320
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.
989 : 1, 23, 43, 989
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
956 : 1, 2, 4, 239, 478, 956
338 : 1, 2, 13, 26, 169, 338
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,735,956,338,761, is 1.
Now, the common factors can be found like this.
989:23x 43
735:3x 5x 7x 7
956:2x 2x 239
338:2x 13x 13
761:761
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 178748695081320/(1x2)
LCM = 178748695081320/2
LCM = 89374347540660
Thus, we can understand that the LCM of 989,735,956,338,761 is 89374347540660.
