HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 787, 8810, 7664 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 787, 8810, 7664 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 787, 8810, 7664 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 787, 8810, 7664 is 1.
HCF(787, 8810, 7664) = 1
HCF of 787, 8810, 7664 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 787, 8810, 7664 is 1.
Highest Common Factor of 787,8810,7664 is 1
Step 1: Since 8810 > 787, we apply the division lemma to 8810 and 787, to get
8810 = 787 x 11 + 153
Step 2: Since the reminder 787 ≠ 0, we apply division lemma to 153 and 787, to get
787 = 153 x 5 + 22
Step 3: We consider the new divisor 153 and the new remainder 22, and apply the division lemma to get
153 = 22 x 6 + 21
We consider the new divisor 22 and the new remainder 21,and apply the division lemma to get
22 = 21 x 1 + 1
We consider the new divisor 21 and the new remainder 1,and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 787 and 8810 is 1
Notice that 1 = HCF(21,1) = HCF(22,21) = HCF(153,22) = HCF(787,153) = HCF(8810,787) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7664 > 1, we apply the division lemma to 7664 and 1, to get
7664 = 1 x 7664 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 7664 is 1
Notice that 1 = HCF(7664,1) .
