HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 640, 9079, 7698 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 640, 9079, 7698 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 640, 9079, 7698 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 640, 9079, 7698 is 1.
HCF(640, 9079, 7698) = 1
HCF of 640, 9079, 7698 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 640, 9079, 7698 is 1.
Highest Common Factor of 640,9079,7698 is 1
Step 1: Since 9079 > 640, we apply the division lemma to 9079 and 640, to get
9079 = 640 x 14 + 119
Step 2: Since the reminder 640 ≠ 0, we apply division lemma to 119 and 640, to get
640 = 119 x 5 + 45
Step 3: We consider the new divisor 119 and the new remainder 45, and apply the division lemma to get
119 = 45 x 2 + 29
We consider the new divisor 45 and the new remainder 29,and apply the division lemma to get
45 = 29 x 1 + 16
We consider the new divisor 29 and the new remainder 16,and apply the division lemma to get
29 = 16 x 1 + 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 640 and 9079 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(29,16) = HCF(45,29) = HCF(119,45) = HCF(640,119) = HCF(9079,640) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7698 > 1, we apply the division lemma to 7698 and 1, to get
7698 = 1 x 7698 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 7698 is 1
Notice that 1 = HCF(7698,1) .
