Find LCM of 738,137,338,980,784 with Prime Factorization


2 738, 137, 338, 980, 784
2 369, 137, 169, 490, 392
7 369, 137, 169, 245, 196
7 369, 137, 169, 35, 28
369, 137, 169, 5, 4

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

2 x 2 x 7 x 7 x 369 x 137 x 169 x 5 x 4 = 33490351440

Therefore, the lowest common multiple of 738,137,338,980,784 is 33490351440.

LCM Formula to Find Lowest Common Multiple of 738,137,338,980,784

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.

738 x 137 x 338 x 980 x 784 = 26256435528960

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.

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

137 : 1, 137

338 : 1, 2, 13, 26, 169, 338

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

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 738,137,338,980,784, is 1.

Now, the common factors can be found like this.

738:2x 3x 3x 41

137:137

338:2x 13x 13

980:2x 2x 5x 7x 7

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 7x 7 = 784

Therefore, the value for common factors is 784.

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 = 26256435528960/(1x784)

LCM = 26256435528960/784

LCM = 33490351440

Thus, we can understand that the LCM of 738,137,338,980,784 is 33490351440.
