Find LCM of 136,989,761,870,986 with Prime Factorization
2 | 136, 989, 761, 870, 986 |
17 | 68, 989, 761, 435, 493 |
29 | 4, 989, 761, 435, 29 |
4, 989, 761, 15, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 29 x 4 x 989 x 761 x 15 x 1 = 44525531640
Therefore, the lowest common multiple of 136,989,761,870,986 is 44525531640.
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.
136 x 989 x 761 x 870 x 986 = 87804348394080
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.
136 : 1, 2, 4, 8, 17, 34, 68, 136
989 : 1, 23, 43, 989
761 : 1, 761
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 136,989,761,870,986, is 1.
Now, the common factors can be found like this.
136:2x 2x 2x 17
989:23x 43
761:761
870:2x 3x 5x 29
986:2x 17x 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 17x 29 = 1972
Therefore, the value for common factors is 1972.
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 = 87804348394080/(1x1972)
LCM = 87804348394080/1972
LCM = 44525531640
Thus, we can understand that the LCM of 136,989,761,870,986 is 44525531640.
