Given numbers are 770,254,784,274,681

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

The LCM of 770,254,784,274,681 is 510916763280.

Find LCM of 770,254,784,274,681 with Prime Factorization

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

2 x 7 x 55 x 127 x 56 x 137 x 681 = 510916763280

Therefore, the lowest common multiple of 770,254,784,274,681 is 510916763280.

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.

770 x 254 x 784 x 274 x 681 = 28611338743680

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.

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

254 : 1, 2, 127, 254

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

274 : 1, 2, 137, 274

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,254,784,274,681, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

254:2x 127

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

274:2x 137

681:3x 227

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 7 = 56

Therefore, the value for common factors is 56.

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 = 28611338743680/(1x56)

LCM = 28611338743680/56

LCM = 510916763280

Thus, we can understand that the LCM of 770,254,784,274,681 is 510916763280.
