Given numbers are 989,712,361,546
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,712,361,546 is 69397868904.
Find LCM of 989,712,361,546 with Prime Factorization
2 | 989, 712, 361, 546 |
989, 356, 361, 273 |
Multiply the prime numbers at the bottom and the left side.
2 x 989 x 356 x 361 x 273 = 69397868904
Therefore, the lowest common multiple of 989,712,361,546 is 69397868904.
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 712 x 361 x 546 = 138795737808
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
712 : 1, 2, 4, 8, 89, 178, 356, 712
361 : 1, 19, 361
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,712,361,546, is 1.
Now, the common factors can be found like this.
989:23x 43
712:2x 2x 2x 89
361:19x 19
546:2x 3x 7x 13
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 = 138795737808/(1x2)
LCM = 138795737808/2
LCM = 69397868904
Thus, we can understand that the LCM of 989,712,361,546 is 69397868904.
