HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 669, 64597 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 669, 64597 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 669, 64597 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 669, 64597 is 1.
HCF(669, 64597) = 1
HCF of 669, 64597 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 669, 64597 is 1.
Highest Common Factor of 669,64597 is 1
Step 1: Since 64597 > 669, we apply the division lemma to 64597 and 669, to get
64597 = 669 x 96 + 373
Step 2: Since the reminder 669 ≠ 0, we apply division lemma to 373 and 669, to get
669 = 373 x 1 + 296
Step 3: We consider the new divisor 373 and the new remainder 296, and apply the division lemma to get
373 = 296 x 1 + 77
We consider the new divisor 296 and the new remainder 77,and apply the division lemma to get
296 = 77 x 3 + 65
We consider the new divisor 77 and the new remainder 65,and apply the division lemma to get
77 = 65 x 1 + 12
We consider the new divisor 65 and the new remainder 12,and apply the division lemma to get
65 = 12 x 5 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 669 and 64597 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(65,12) = HCF(77,65) = HCF(296,77) = HCF(373,296) = HCF(669,373) = HCF(64597,669) .
