Given numbers are 377,128,689,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 377,128,689,921 is 2355520128.
Find LCM of 377,128,689,921 with Prime Factorization
13 | 377, 128, 689, 921 |
29, 128, 53, 921 |
Multiply the prime numbers at the bottom and the left side.
13 x 29 x 128 x 53 x 921 = 2355520128
Therefore, the lowest common multiple of 377,128,689,921 is 2355520128.
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.
377 x 128 x 689 x 921 = 30621761664
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.
377 : 1, 13, 29, 377
128 : 1, 2, 4, 8, 16, 32, 64, 128
689 : 1, 13, 53, 689
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 377,128,689,921, is 1.
Now, the common factors can be found like this.
377:13x 29
128:2x 2x 2x 2x 2x 2x 2
689:13x 53
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 30621761664/(1x13)
LCM = 30621761664/13
LCM = 2355520128
Thus, we can understand that the LCM of 377,128,689,921 is 2355520128.
