Calculate the LCM of 974,945,640,719

Given numbers are 974,945,640,719

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

The LCM of 974,945,640,719 is 42354506880.

Find LCM of 974,945,640,719 with Prime Factorization


2 974, 945, 640, 719
5 487, 945, 320, 719
487, 189, 64, 719

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

2 x 5 x 487 x 189 x 64 x 719 = 42354506880

Therefore, the lowest common multiple of 974,945,640,719 is 42354506880.

LCM Formula to Find Lowest Common Multiple of 974,945,640,719

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.

974 x 945 x 640 x 719 = 423545068800

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.

974 : 1, 2, 487, 974

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

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

719 : 1, 719

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,945,640,719, is 1.

Now, the common factors can be found like this.

974:2x 487

945:3x 3x 3x 5x 7

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

719:719

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 = 423545068800/(1x10)

LCM = 423545068800/10

LCM = 42354506880

Thus, we can understand that the LCM of 974,945,640,719 is 42354506880.
