10, 20, 30, 40, 50, 60, 70, 80, 90
Just twos and fives: 10, 20, 40, 50 and 80
That number would be 2 X 3 X 5 = 30.
10, 20, 30, 40, 50, 60, 70, 80, 90
They are 10 and any multiples of 10
10
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.
10, 20, 30, 40, 50, 60, 70, 80, 90
4, 9, 25 and 49 They are squares of prime numbers.
There is no LCM for less than two numbers. LCM is the multiple of the highest power of prime factors in two or more numbers. Example: LCM 0f 9, 15, and 25 is 225, which is the multiple of the highest power of prime factors in 9, 15, and 25 (32 x 52).
If the GCF of two numbers is 1, their LCM will be their product. Such numbers are called relatively prime, or co-prime. Any two prime numbers (like 3 and 5) will be that way, but the numbers don't have to be prime (like 4 and 9).
If none of the prime factors are in common, the LCM will be the product of the two.
No
for s being prime find all s so that s² < 50 { 4 , 25 , 49...and one more }
2,3,5,7,11,13,17,19,23,and 29
59 - 2 = 57
19 - 2 = 17

97-2=95 The answer is 95
