Calculate the LCM of 964,385,764,784

Given numbers are 964,385,764,784

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 964,385,764,784 is 1984856720.

Find LCM of 964,385,764,784 with Prime Factorization


2 964, 385, 764, 784
2 482, 385, 382, 392
7 241, 385, 191, 196
241, 55, 191, 28

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 7 x 241 x 55 x 191 x 28 = 1984856720

Therefore, the lowest common multiple of 964,385,764,784 is 1984856720.

LCM Formula to Find Lowest Common Multiple of 964,385,764,784

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.

964 x 385 x 764 x 784 = 222303952640

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.

964 : 1, 2, 4, 241, 482, 964

385 : 1, 5, 7, 11, 35, 55, 77, 385

764 : 1, 2, 4, 191, 382, 764

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 964,385,764,784, is 1.

Now, the common factors can be found like this.

964:2x 2x 241

385:5x 7x 11

764:2x 2x 191

784:2x 2x 2x 2x 7x 7

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 2x 2x 7 = 112

Therefore, the value for common factors is 112.

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 = 222303952640/(1x112)

LCM = 222303952640/112

LCM = 1984856720

Thus, we can understand that the LCM of 964,385,764,784 is 1984856720.
