HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 628, 512 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 628, 512 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, 512 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, 512 is 4.
HCF(628, 512) = 4
HCF of 628, 512 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, 512 is 4.
Highest Common Factor of 628,512 is 4
Step 1: Since 628 > 512, we apply the division lemma to 628 and 512, to get
628 = 512 x 1 + 116
Step 2: Since the reminder 512 ≠ 0, we apply division lemma to 116 and 512, to get
512 = 116 x 4 + 48
Step 3: We consider the new divisor 116 and the new remainder 48, and apply the division lemma to get
116 = 48 x 2 + 20
We consider the new divisor 48 and the new remainder 20,and apply the division lemma to get
48 = 20 x 2 + 8
We consider the new divisor 20 and the new remainder 8,and apply the division lemma to get
20 = 8 x 2 + 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 512 is 4
Notice that 4 = HCF(8,4) = HCF(20,8) = HCF(48,20) = HCF(116,48) = HCF(512,116) = HCF(628,512) .
