HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 651, 425 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 651, 425 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 651, 425 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 651, 425 is 1.
HCF(651, 425) = 1
HCF of 651, 425 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 651, 425 is 1.
Highest Common Factor of 651,425 is 1
Step 1: Since 651 > 425, we apply the division lemma to 651 and 425, to get
651 = 425 x 1 + 226
Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 226 and 425, to get
425 = 226 x 1 + 199
Step 3: We consider the new divisor 226 and the new remainder 199, and apply the division lemma to get
226 = 199 x 1 + 27
We consider the new divisor 199 and the new remainder 27,and apply the division lemma to get
199 = 27 x 7 + 10
We consider the new divisor 27 and the new remainder 10,and apply the division lemma to get
27 = 10 x 2 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 651 and 425 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(27,10) = HCF(199,27) = HCF(226,199) = HCF(425,226) = HCF(651,425) .
