HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 651, 923, 944 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 651, 923, 944 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, 923, 944 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, 923, 944 is 1.
HCF(651, 923, 944) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 651, 923, 944 is 1.
Step 1: Since 923 > 651, we apply the division lemma to 923 and 651, to get
923 = 651 x 1 + 272
Step 2: Since the reminder 651 ≠ 0, we apply division lemma to 272 and 651, to get
651 = 272 x 2 + 107
Step 3: We consider the new divisor 272 and the new remainder 107, and apply the division lemma to get
272 = 107 x 2 + 58
We consider the new divisor 107 and the new remainder 58,and apply the division lemma to get
107 = 58 x 1 + 49
We consider the new divisor 58 and the new remainder 49,and apply the division lemma to get
58 = 49 x 1 + 9
We consider the new divisor 49 and the new remainder 9,and apply the division lemma to get
49 = 9 x 5 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 651 and 923 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(49,9) = HCF(58,49) = HCF(107,58) = HCF(272,107) = HCF(651,272) = HCF(923,651) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 944 > 1, we apply the division lemma to 944 and 1, to get
944 = 1 x 944 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 944 is 1
Notice that 1 = HCF(944,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
