What is it called when the product of a pair of numbers is the LCM also?
The numbers are relatively prime, or co-prime.
What is the least common multiple of 20 and 21?
The LCM of 20 and 21 is 420. The LCM of any pair of consecutive integers is their product.
How do you find a pair of whole numbers whose product is 280 and whose LCM is 140?
They are 2 and 140 because their LCM is 140 and their product is 280
How can you determine if the least common multiple of 2 numbers is the product of the 2 numbers or less than the product of the 2 numbers?
If the GCF of a given pair of numbers is 1, the LCM will be equal to their product. If the GCF is greater than 1, the LCM will be less than their product. Or, stated another way, if the two numbers have no common prime factors, their LCM will be their product.
Is the LCM of a pair of numbers ever less than both numbers?
The LCM for any pair of natural numbers can be as big as their product.
What is the product of the GCF and LCM of two numbers?
The product of the GCF and LCM of a pair of numbers is equal to the product of the numbers.
What is it called when the product of a pair of numbers is the LCM also?
The numbers are relatively prime, or co-prime.
What is the Multiplication of HCF and LCM of two number?
The product of the GCF and LCM of a pair of numbers is equal to the product of the numbers.
What relationship does the GCF have with LCM?
It's kind of inverse. The product of the GCF and LCM of a pair of numbers will equal the product of the original numbers.
What is the least common multiple of 20 and 21?
The LCM of 20 and 21 is 420. The LCM of any pair of consecutive integers is their product.
How do you find two numbers if HCF and LCM are known?
The product of the GCF and the LCM of two numbers is equal to the product of the original two numbers. Multiply the GCF and the LCM. The original two numbers will be another factor pair of that total. Find the factor pair that has that GCF and LCM.
How do you find a pair of whole numbers whose product is 280 and whose LCM is 140?
They are 2 and 140 because their LCM is 140 and their product is 280
How do you work out which 2 numbers have an lcm of 30 and an HCF of 3?
In these types of problems, the numbers can also be the answer. 3 and 30 have a GCF of 3 and an LCM of 30. Since the product of the GCF and LCM of two numbers is the same as the product of the numbers, you could also use another factor pair of 90, like 6 and 15.
What is the least common multiple of 6 and 37?
The LCM of 6 and 37 is 222. Because 37 is prime, the LCM of the pair is their product.
What is the product of the GCF and LCM of 4 and 6?
2 x 12 = 24, but there's an easier way if you remember that the product of the GCF and LCM of a pair of numbers will always be equal to the product of the two numbers.
Find a pair of whole numbers whose product is 280 and whose LCM is 140?
10 and 28
Find a pair of whole numbers whose product is 280 and whose lcm is 140-?
They are: 2 and 140
