Given numbers are 154,628,774,411,971
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,628,774,411,971 is 2489436947844.
Find LCM of 154,628,774,411,971 with Prime Factorization
2 | 154, 628, 774, 411, 971 |
3 | 77, 314, 387, 411, 971 |
77, 314, 129, 137, 971 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 77 x 314 x 129 x 137 x 971 = 2489436947844
Therefore, the lowest common multiple of 154,628,774,411,971 is 2489436947844.
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.
154 x 628 x 774 x 411 x 971 = 29873243374128
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
628 : 1, 2, 4, 157, 314, 628
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
411 : 1, 3, 137, 411
971 : 1, 971
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,628,774,411,971, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
628:2x 2x 157
774:2x 3x 3x 43
411:3x 137
971:971
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 3 = 12
Therefore, the value for common factors is 12.
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 = 29873243374128/(1x12)
LCM = 29873243374128/12
LCM = 2489436947844
Thus, we can understand that the LCM of 154,628,774,411,971 is 2489436947844.
