Given numbers are 357,685,161,274
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 357,685,161,274 is 11249070.
Find LCM of 357,685,161,274 with Prime Factorization
7 | 357, 685, 161, 274 |
137 | 51, 685, 23, 274 |
51, 5, 23, 2 |
Multiply the prime numbers at the bottom and the left side.
7 x 137 x 51 x 5 x 23 x 2 = 11249070
Therefore, the lowest common multiple of 357,685,161,274 is 11249070.
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.
357 x 685 x 161 x 274 = 10787858130
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.
357 : 1, 3, 7, 17, 21, 51, 119, 357
685 : 1, 5, 137, 685
161 : 1, 7, 23, 161
274 : 1, 2, 137, 274
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 357,685,161,274, is 1.
Now, the common factors can be found like this.
357:3x 7x 17
685:5x 137
161:7x 23
274:2x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 137 = 959
Therefore, the value for common factors is 959.
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 = 10787858130/(1x959)
LCM = 10787858130/959
LCM = 11249070
Thus, we can understand that the LCM of 357,685,161,274 is 11249070.
