380 = 2 * 19 * 2 * 5
1250 = 2 * 5 * 5 * 5 * 5
HCF of 380 & 1250 = 2 * 5 = 10
LCM of 380 & 1250 = 10 * 19 * 2 * 125 = 47500

Step-by-step explanation:
Steps to find LCM
Find the prime factorization of 380
380 = 2 × 2 × 5 × 19
Find the prime factorization of 1250
1250 = 2 × 5 × 5 × 5 × 5
Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the lcm:
LCM = 2 × 2 × 5 × 5 × 5 × 5 × 19
LCM = 47500
Steps to find HCF
Find the prime factorization of 380
380 = 2 × 2 × 5 × 19
Find the prime factorization of 1250
1250 = 2 × 5 × 5 × 5 × 5
To find the gcf, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 5
GCF = 10
