Given numbers are 640,474,714,306

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

The LCM of 640,474,714,306 is 54149760.

Find LCM of 640,474,714,306 with Prime Factorization

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

2 x 3 x 17 x 320 x 79 x 7 x 3 = 54149760

Therefore, the lowest common multiple of 640,474,714,306 is 54149760.

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.

640 x 474 x 714 x 306 = 66279306240

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.

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

474 : 1, 2, 3, 6, 79, 158, 237, 474

714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,474,714,306, is 2.

Now, the common factors can be found like this.

640:2x 2x 2x 2x 2x 2x 2x 5

474:2x 3x 79

714:2x 3x 7x 17

306:2x 3x 3x 17

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 3x 3x 17 = 612

Therefore, the value for common factors is 612.

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 = 66279306240/(2x612)

LCM = 66279306240/1224

LCM = 54149760

Thus, we can understand that the LCM of 640,474,714,306 is 54149760.
