HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 638, 286 i.e. 22 the largest integer that leaves a remainder zero for all numbers.
HCF of 638, 286 is 22 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, 286 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, 286 is 22.
HCF(638, 286) = 22
HCF of 638, 286 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, 286 is 22.
Highest Common Factor of 638,286 is 22
Step 1: Since 638 > 286, we apply the division lemma to 638 and 286, to get
638 = 286 x 2 + 66
Step 2: Since the reminder 286 ≠ 0, we apply division lemma to 66 and 286, to get
286 = 66 x 4 + 22
Step 3: We consider the new divisor 66 and the new remainder 22, and apply the division lemma to get
66 = 22 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 22, the HCF of 638 and 286 is 22
Notice that 22 = HCF(66,22) = HCF(286,66) = HCF(638,286) .
