HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 899, 644 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 899, 644 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 899, 644 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 899, 644 is 1.
HCF(899, 644) = 1
HCF of 899, 644 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 899, 644 is 1.
Highest Common Factor of 899,644 is 1
Step 1: Since 899 > 644, we apply the division lemma to 899 and 644, to get
899 = 644 x 1 + 255
Step 2: Since the reminder 644 ≠ 0, we apply division lemma to 255 and 644, to get
644 = 255 x 2 + 134
Step 3: We consider the new divisor 255 and the new remainder 134, and apply the division lemma to get
255 = 134 x 1 + 121
We consider the new divisor 134 and the new remainder 121,and apply the division lemma to get
134 = 121 x 1 + 13
We consider the new divisor 121 and the new remainder 13,and apply the division lemma to get
121 = 13 x 9 + 4
We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get
13 = 4 x 3 + 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 899 and 644 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(121,13) = HCF(134,121) = HCF(255,134) = HCF(644,255) = HCF(899,644) .
