LCM Formula to Find Lowest Common Multiple of 882,784,938,690,821

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.

882 x 784 x 938 x 690 x 821 = 367434332818560

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.

882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882

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

938 : 1, 2, 7, 14, 67, 134, 469, 938

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 882,784,938,690,821, is 1.

Now, the common factors can be found like this.

882:2x 3x 3x 7x 7

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

938:2x 7x 67

690:2x 3x 5x 23

821:821

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 3x 7x 7x 7 = 8232

Therefore, the value for common factors is 8232.

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 = 367434332818560/(1x8232)

LCM = 367434332818560/8232

LCM = 44634880080

Thus, we can understand that the LCM of 882,784,938,690,821 is 44634880080.
