HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 626, 66898 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 626, 66898 is 2 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 626, 66898 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 626, 66898 is 2.
HCF(626, 66898) = 2
HCF of 626, 66898 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 626, 66898 is 2.
Highest Common Factor of 626,66898 is 2
Step 1: Since 66898 > 626, we apply the division lemma to 66898 and 626, to get
66898 = 626 x 106 + 542
Step 2: Since the reminder 626 ≠ 0, we apply division lemma to 542 and 626, to get
626 = 542 x 1 + 84
Step 3: We consider the new divisor 542 and the new remainder 84, and apply the division lemma to get
542 = 84 x 6 + 38
We consider the new divisor 84 and the new remainder 38,and apply the division lemma to get
84 = 38 x 2 + 8
We consider the new divisor 38 and the new remainder 8,and apply the division lemma to get
38 = 8 x 4 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 626 and 66898 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(38,8) = HCF(84,38) = HCF(542,84) = HCF(626,542) = HCF(66898,626) .
