HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 380, 571, 28 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 380, 571, 28 is 1 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 380, 571, 28 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 380, 571, 28 is 1.
HCF(380, 571, 28) = 1
HCF of 380, 571, 28 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 380, 571, 28 is 1.
Highest Common Factor of 380,571,28 is 1
Step 1: Since 571 > 380, we apply the division lemma to 571 and 380, to get
571 = 380 x 1 + 191
Step 2: Since the reminder 380 ≠ 0, we apply division lemma to 191 and 380, to get
380 = 191 x 1 + 189
Step 3: We consider the new divisor 191 and the new remainder 189, and apply the division lemma to get
191 = 189 x 1 + 2
We consider the new divisor 189 and the new remainder 2,and apply the division lemma to get
189 = 2 x 94 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 380 and 571 is 1
Notice that 1 = HCF(2,1) = HCF(189,2) = HCF(191,189) = HCF(380,191) = HCF(571,380) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 28 > 1, we apply the division lemma to 28 and 1, to get
28 = 1 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 28 is 1
Notice that 1 = HCF(28,1) .
