HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 634, 3661 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 634, 3661 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 634, 3661 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 634, 3661 is 1.
HCF(634, 3661) = 1
HCF of 634, 3661 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 634, 3661 is 1.
Highest Common Factor of 634,3661 is 1
Step 1: Since 3661 > 634, we apply the division lemma to 3661 and 634, to get
3661 = 634 x 5 + 491
Step 2: Since the reminder 634 ≠ 0, we apply division lemma to 491 and 634, to get
634 = 491 x 1 + 143
Step 3: We consider the new divisor 491 and the new remainder 143, and apply the division lemma to get
491 = 143 x 3 + 62
We consider the new divisor 143 and the new remainder 62,and apply the division lemma to get
143 = 62 x 2 + 19
We consider the new divisor 62 and the new remainder 19,and apply the division lemma to get
62 = 19 x 3 + 5
We consider the new divisor 19 and the new remainder 5,and apply the division lemma to get
19 = 5 x 3 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 634 and 3661 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(62,19) = HCF(143,62) = HCF(491,143) = HCF(634,491) = HCF(3661,634) .
