HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 651, 970, 824 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 651, 970, 824 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 651, 970, 824 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 651, 970, 824 is 1.
HCF(651, 970, 824) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 651, 970, 824 is 1.
Step 1: Since 970 > 651, we apply the division lemma to 970 and 651, to get
970 = 651 x 1 + 319
Step 2: Since the reminder 651 ≠ 0, we apply division lemma to 319 and 651, to get
651 = 319 x 2 + 13
Step 3: We consider the new divisor 319 and the new remainder 13, and apply the division lemma to get
319 = 13 x 24 + 7
We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get
13 = 7 x 1 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 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 651 and 970 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(319,13) = HCF(651,319) = HCF(970,651) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 824 > 1, we apply the division lemma to 824 and 1, to get
824 = 1 x 824 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 824 is 1
Notice that 1 = HCF(824,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
