This cannot be determined because the common multiples of any two or more numbers are infinite.
The common factors of 90 and 189 are 1, 3 and 9.
The lowest common multiple is 90 .There is no highest one. If you think you've found the highest one,just add 90 to it, and you'll have a higher common multiple. You cancontinue doing that forever.
It is important to note that there is no such thing as a greatest common multiple - but as a lowest common multiple and a highest common factor.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 135 and 189 is 27
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 of 18 and 90 is 90.
The GCF is 9.
The GCF is 9.
The least common multiple of the numbers 210 and 90 is 630.
The least common multiple of 7 , 90 = 630
The least common multiple of 96 , 90 = 1,440
The least common multiple of 36 and 90 is 180.
