HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 628, 968 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 628, 968 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, 968 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, 968 is 4.
HCF(628, 968) = 4
HCF of 628, 968 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, 968 is 4.
Highest Common Factor of 628,968 is 4
Step 1: Since 968 > 628, we apply the division lemma to 968 and 628, to get
968 = 628 x 1 + 340
Step 2: Since the reminder 628 ≠ 0, we apply division lemma to 340 and 628, to get
628 = 340 x 1 + 288
Step 3: We consider the new divisor 340 and the new remainder 288, and apply the division lemma to get
340 = 288 x 1 + 52
We consider the new divisor 288 and the new remainder 52,and apply the division lemma to get
288 = 52 x 5 + 28
We consider the new divisor 52 and the new remainder 28,and apply the division lemma to get
52 = 28 x 1 + 24
We consider the new divisor 28 and the new remainder 24,and apply the division lemma to get
28 = 24 x 1 + 4
We consider the new divisor 24 and the new remainder 4,and apply the division lemma to get
24 = 4 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 628 and 968 is 4
Notice that 4 = HCF(24,4) = HCF(28,24) = HCF(52,28) = HCF(288,52) = HCF(340,288) = HCF(628,340) = HCF(968,628) .
