It is infinity but the LCM of the given three numbers is 54
Since 54 is a multiple of 18, it is automatically the LCM.
The least common multiple of 5 18 and 54 is 270
There is no highest common multiple of any two or more numbers, for whatever multiple is stated, their LOWEST common multiple can be added to get an even higher common multiple. However, there is a highest common FACTOR (HCF) which is the largest positive number that divides all the numbers without a remainder, and a LOWEST common multiple (LCM) which is the smallest number into which all the numbers divide without a remainder. For 108, 54, 90: hcf(108, 54, 90) = 18 lcm(108, 54, 90) = 540
The Least Common Multiple (LCM) for 16 18 54 is 432.
Least Common Multiple (LCM) for 18 54 is 54
54
54
The lowest common multiple of 18 and 54 is 108. 54 times 2 equals 108, and 18 times 6 equals 108.
The highest common factor of 54 and 90 is 18
9
The LCM is 270. The GCM is infinite.
The least common multiple of 9, 18, and 27 is 54.
