Given numbers are 681,338,695,145,434
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,338,695,145,434 is 1006714557030.
Find LCM of 681,338,695,145,434 with Prime Factorization
2 | 681, 338, 695, 145, 434 |
5 | 681, 169, 695, 145, 217 |
681, 169, 139, 29, 217 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 681 x 169 x 139 x 29 x 217 = 1006714557030
Therefore, the lowest common multiple of 681,338,695,145,434 is 1006714557030.
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.
681 x 338 x 695 x 145 x 434 = 10067145570300
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.
681 : 1, 3, 227, 681
338 : 1, 2, 13, 26, 169, 338
695 : 1, 5, 139, 695
145 : 1, 5, 29, 145
434 : 1, 2, 7, 14, 31, 62, 217, 434
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,338,695,145,434, is 1.
Now, the common factors can be found like this.
681:3x 227
338:2x 13x 13
695:5x 139
145:5x 29
434:2x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 10067145570300/(1x10)
LCM = 10067145570300/10
LCM = 1006714557030
Thus, we can understand that the LCM of 681,338,695,145,434 is 1006714557030.
