HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 626, 988, 458 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 626, 988, 458 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, 988, 458 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, 988, 458 is 2.
HCF(626, 988, 458) = 2
HCF of 626, 988, 458 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, 988, 458 is 2.
Highest Common Factor of 626,988,458 is 2
Step 1: Since 988 > 626, we apply the division lemma to 988 and 626, to get
988 = 626 x 1 + 362
Step 2: Since the reminder 626 ≠ 0, we apply division lemma to 362 and 626, to get
626 = 362 x 1 + 264
Step 3: We consider the new divisor 362 and the new remainder 264, and apply the division lemma to get
362 = 264 x 1 + 98
We consider the new divisor 264 and the new remainder 98,and apply the division lemma to get
264 = 98 x 2 + 68
We consider the new divisor 98 and the new remainder 68,and apply the division lemma to get
98 = 68 x 1 + 30
We consider the new divisor 68 and the new remainder 30,and apply the division lemma to get
68 = 30 x 2 + 8
We consider the new divisor 30 and the new remainder 8,and apply the division lemma to get
30 = 8 x 3 + 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 988 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(30,8) = HCF(68,30) = HCF(98,68) = HCF(264,98) = HCF(362,264) = HCF(626,362) = HCF(988,626) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 458 > 2, we apply the division lemma to 458 and 2, to get
458 = 2 x 229 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 458 is 2
Notice that 2 = HCF(458,2) .
