Calculate the LCM of 131,769,350,518,781

Given numbers are 131,769,350,518,781

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

The LCM of 131,769,350,518,781 is 1018869209050.

Find LCM of 131,769,350,518,781 with Prime Factorization


2 131, 769, 350, 518, 781
7 131, 769, 175, 259, 781
131, 769, 25, 37, 781

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

2 x 7 x 131 x 769 x 25 x 37 x 781 = 1018869209050

Therefore, the lowest common multiple of 131,769,350,518,781 is 1018869209050.

LCM Formula to Find Lowest Common Multiple of 131,769,350,518,781

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.

131 x 769 x 350 x 518 x 781 = 14264168926700

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.

131 : 1, 131

769 : 1, 769

350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350

518 : 1, 2, 7, 14, 37, 74, 259, 518

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,769,350,518,781, is 1.

Now, the common factors can be found like this.

131:131

769:769

350:2x 5x 5x 7

518:2x 7x 37

781:11x 71

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 14264168926700/(1x14)

LCM = 14264168926700/14

LCM = 1018869209050

Thus, we can understand that the LCM of 131,769,350,518,781 is 1018869209050.
