LCM Formula to Find Lowest Common Multiple of 655,208,821,690

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.

655 x 208 x 821 x 690 = 77178597600

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.

655 : 1, 5, 131, 655

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

821 : 1, 821

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,208,821,690, is 1.

Now, the common factors can be found like this.

655:5x 131

208:2x 2x 2x 2x 13

821:821

690:2x 3x 5x 23

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 = 77178597600/(1x10)

LCM = 77178597600/10

LCM = 7717859760

Thus, we can understand that the LCM of 655,208,821,690 is 7717859760.
