HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 966, 489, 663, 683 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 966, 489, 663, 683 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 966, 489, 663, 683 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 966, 489, 663, 683 is 1.
HCF(966, 489, 663, 683) = 1
HCF of 966, 489, 663, 683 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 966, 489, 663, 683 is 1.
Highest Common Factor of 966,489,663,683 is 1
Step 1: Since 966 > 489, we apply the division lemma to 966 and 489, to get
966 = 489 x 1 + 477
Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 477 and 489, to get
489 = 477 x 1 + 12
Step 3: We consider the new divisor 477 and the new remainder 12, and apply the division lemma to get
477 = 12 x 39 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 966 and 489 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(477,12) = HCF(489,477) = HCF(966,489) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 663 > 3, we apply the division lemma to 663 and 3, to get
663 = 3 x 221 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 663 is 3
Notice that 3 = HCF(663,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 683 > 3, we apply the division lemma to 683 and 3, to get
683 = 3 x 227 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 683 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(683,3) .
