HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 644, 801 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 644, 801 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 644, 801 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 644, 801 is 1.
HCF(644, 801) = 1
HCF of 644, 801 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 644, 801 is 1.
Highest Common Factor of 644,801 is 1
Step 1: Since 801 > 644, we apply the division lemma to 801 and 644, to get
801 = 644 x 1 + 157
Step 2: Since the reminder 644 ≠ 0, we apply division lemma to 157 and 644, to get
644 = 157 x 4 + 16
Step 3: We consider the new divisor 157 and the new remainder 16, and apply the division lemma to get
157 = 16 x 9 + 13
We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get
16 = 13 x 1 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 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 644 and 801 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(157,16) = HCF(644,157) = HCF(801,644) .
