HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 658, 831, 784 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 658, 831, 784 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 658, 831, 784 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 658, 831, 784 is 1.
HCF(658, 831, 784) = 1
HCF of 658, 831, 784 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 658, 831, 784 is 1.
Highest Common Factor of 658,831,784 is 1
Step 1: Since 831 > 658, we apply the division lemma to 831 and 658, to get
831 = 658 x 1 + 173
Step 2: Since the reminder 658 ≠ 0, we apply division lemma to 173 and 658, to get
658 = 173 x 3 + 139
Step 3: We consider the new divisor 173 and the new remainder 139, and apply the division lemma to get
173 = 139 x 1 + 34
We consider the new divisor 139 and the new remainder 34,and apply the division lemma to get
139 = 34 x 4 + 3
We consider the new divisor 34 and the new remainder 3,and apply the division lemma to get
34 = 3 x 11 + 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 658 and 831 is 1
Notice that 1 = HCF(3,1) = HCF(34,3) = HCF(139,34) = HCF(173,139) = HCF(658,173) = HCF(831,658) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 784 > 1, we apply the division lemma to 784 and 1, to get
784 = 1 x 784 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 784 is 1
Notice that 1 = HCF(784,1) .
