HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 638, 374, 852 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 638, 374, 852 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 638, 374, 852 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 638, 374, 852 is 2.
HCF(638, 374, 852) = 2
HCF of 638, 374, 852 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 638, 374, 852 is 2.
Highest Common Factor of 638,374,852 is 2
Step 1: Since 638 > 374, we apply the division lemma to 638 and 374, to get
638 = 374 x 1 + 264
Step 2: Since the reminder 374 ≠ 0, we apply division lemma to 264 and 374, to get
374 = 264 x 1 + 110
Step 3: We consider the new divisor 264 and the new remainder 110, and apply the division lemma to get
264 = 110 x 2 + 44
We consider the new divisor 110 and the new remainder 44,and apply the division lemma to get
110 = 44 x 2 + 22
We consider the new divisor 44 and the new remainder 22,and apply the division lemma to get
44 = 22 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 22, the HCF of 638 and 374 is 22
Notice that 22 = HCF(44,22) = HCF(110,44) = HCF(264,110) = HCF(374,264) = HCF(638,374) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 852 > 22, we apply the division lemma to 852 and 22, to get
852 = 22 x 38 + 16
Step 2: Since the reminder 22 ≠ 0, we apply division lemma to 16 and 22, to get
22 = 16 x 1 + 6
Step 3: We consider the new divisor 16 and the new remainder 6, and apply the division lemma to get
16 = 6 x 2 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 22 and 852 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(22,16) = HCF(852,22) .
