Given numbers are 711,990,455,258,974

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

The LCM of 711,990,455,258,974 is 149039400510.

Find LCM of 711,990,455,258,974 with Prime Factorization

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

2 x 3 x 3 x 5 x 79 x 11 x 91 x 43 x 487 = 149039400510

Therefore, the lowest common multiple of 711,990,455,258,974 is 149039400510.

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.

711 x 990 x 455 x 258 x 974 = 80481276275400

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.

711 : 1, 3, 9, 79, 237, 711

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

455 : 1, 5, 7, 13, 35, 65, 91, 455

258 : 1, 2, 3, 6, 43, 86, 129, 258

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,990,455,258,974, is 1.

Now, the common factors can be found like this.

711:3x 3x 79

990:2x 3x 3x 5x 11

455:5x 7x 13

258:2x 3x 43

974:2x 487

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 3x 5 = 540

Therefore, the value for common factors is 540.

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 = 80481276275400/(1x540)

LCM = 80481276275400/540

LCM = 149039400510

Thus, we can understand that the LCM of 711,990,455,258,974 is 149039400510.
