Oh, dude, you're hitting me with some math here! So, like, the two prime numbers that multiply to make 91 are 7 and 13. Yeah, it's like a little math puzzle, but hey, I got your back on this one!
The least common multiple of 7 and 13 is 91. Because the numbers in the set are prime, their LCM is their product.
To identify the GCF of 91 and 78, you first need to break these down into their prime factors: 91 = 7x13 78 = 2x3x13 The next step is to identify any common prime factors. In this case, both numbers have 13 as a prime factor. Thus the greatest common factor of 91 and 78 is 13.
560 is a multiple of 7. It goes in 80 times. 91 is a multiple of 7. It goes in 13 times.
The greatest common factor (GCF) of three numbers is the largest number that divides each of the three numbers without leaving a remainder. To find the GCF of 91, 21, and 49, we need to factorize each number. The prime factors of 91 are 7 and 13, the prime factors of 21 are 3 and 7, and the prime factors of 49 are 7 and 7. The common factor among them is 7, so the GCF of 91, 21, and 49 is 7.
The factors of 91 are: 1 7 13 91 The prime factors are: 7 and 13
7 and 13
They are: 7 times 13 = 91
They are 7 times 13 = 91
91 = 7 x 13
7 x 13
No.
91 is the only composite factor of 91. 7 and 13 are prime.
7 x 13 89 + 2
The three prime numbers that add up to 99 are 3, 5, and 91. However, 91 is not a prime number, so a combination of prime numbers that sums to 99 doesn't exist. The only way to express 99 as a sum of prime numbers would involve at least one composite number.
91 is one of the numbers which has prime factors. 91=13 x 7. Here, 13 & 7 both are prime numbers.
127 is prime. 91 has more than two factors.
A person unfamiliar with prime numbers could mistake 51, 91, or any other composite number for a prime number if the person did not factor the number to make sure it had no other factors then 1 and itself.
