HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 628, 32 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 628, 32 is 4 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 628, 32 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 628, 32 is 4.
HCF(628, 32) = 4
HCF of 628, 32 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 628, 32 is 4.
Highest Common Factor of 628,32 is 4
Step 1: Since 628 > 32, we apply the division lemma to 628 and 32, to get
628 = 32 x 19 + 20
Step 2: Since the reminder 32 ≠ 0, we apply division lemma to 20 and 32, to get
32 = 20 x 1 + 12
Step 3: We consider the new divisor 20 and the new remainder 12, and apply the division lemma to get
20 = 12 x 1 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 628 and 32 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(32,20) = HCF(628,32) .
