HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 425, 68446 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 425, 68446 is 1 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 425, 68446 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 425, 68446 is 1.
HCF(425, 68446) = 1
HCF of 425, 68446 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 425, 68446 is 1.
Highest Common Factor of 425,68446 is 1
Step 1: Since 68446 > 425, we apply the division lemma to 68446 and 425, to get
68446 = 425 x 161 + 21
Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 21 and 425, to get
425 = 21 x 20 + 5
Step 3: We consider the new divisor 21 and the new remainder 5, and apply the division lemma to get
21 = 5 x 4 + 1
We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 425 and 68446 is 1
Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(425,21) = HCF(68446,425) .
