HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 660, 8689, 7999 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 660, 8689, 7999 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 660, 8689, 7999 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 660, 8689, 7999 is 1.
HCF(660, 8689, 7999) = 1
HCF of 660, 8689, 7999 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 660, 8689, 7999 is 1.
Highest Common Factor of 660,8689,7999 is 1
Step 1: Since 8689 > 660, we apply the division lemma to 8689 and 660, to get
8689 = 660 x 13 + 109
Step 2: Since the reminder 660 ≠ 0, we apply division lemma to 109 and 660, to get
660 = 109 x 6 + 6
Step 3: We consider the new divisor 109 and the new remainder 6, and apply the division lemma to get
109 = 6 x 18 + 1
We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 660 and 8689 is 1
Notice that 1 = HCF(6,1) = HCF(109,6) = HCF(660,109) = HCF(8689,660) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7999 > 1, we apply the division lemma to 7999 and 1, to get
7999 = 1 x 7999 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 7999 is 1
Notice that 1 = HCF(7999,1) .
