HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 800, 380 i.e. 20 the largest integer that leaves a remainder zero for all numbers.
HCF of 800, 380 is 20 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 800, 380 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 800, 380 is 20.
HCF(800, 380) = 20
HCF of 800, 380 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 800, 380 is 20.
Highest Common Factor of 800,380 is 20
Step 1: Since 800 > 380, we apply the division lemma to 800 and 380, to get
800 = 380 x 2 + 40
Step 2: Since the reminder 380 ≠ 0, we apply division lemma to 40 and 380, to get
380 = 40 x 9 + 20
Step 3: We consider the new divisor 40 and the new remainder 20, and apply the division lemma to get
40 = 20 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 800 and 380 is 20
Notice that 20 = HCF(40,20) = HCF(380,40) = HCF(800,380) .
