HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 899, 640 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 899, 640 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, 640 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, 640 is 1.
HCF(899, 640) = 1
HCF of 899, 640 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, 640 is 1.
Highest Common Factor of 899,640 is 1
Step 1: Since 899 > 640, we apply the division lemma to 899 and 640, to get
899 = 640 x 1 + 259
Step 2: Since the reminder 640 ≠ 0, we apply division lemma to 259 and 640, to get
640 = 259 x 2 + 122
Step 3: We consider the new divisor 259 and the new remainder 122, and apply the division lemma to get
259 = 122 x 2 + 15
We consider the new divisor 122 and the new remainder 15,and apply the division lemma to get
122 = 15 x 8 + 2
We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get
15 = 2 x 7 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 899 and 640 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(122,15) = HCF(259,122) = HCF(640,259) = HCF(899,640) .
