HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 917, 651, 923 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 917, 651, 923 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 917, 651, 923 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 917, 651, 923 is 1.
HCF(917, 651, 923) = 1
HCF of 917, 651, 923 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 917, 651, 923 is 1.
Highest Common Factor of 917,651,923 is 1
Step 1: Since 917 > 651, we apply the division lemma to 917 and 651, to get
917 = 651 x 1 + 266
Step 2: Since the reminder 651 ≠ 0, we apply division lemma to 266 and 651, to get
651 = 266 x 2 + 119
Step 3: We consider the new divisor 266 and the new remainder 119, and apply the division lemma to get
266 = 119 x 2 + 28
We consider the new divisor 119 and the new remainder 28,and apply the division lemma to get
119 = 28 x 4 + 7
We consider the new divisor 28 and the new remainder 7,and apply the division lemma to get
28 = 7 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 917 and 651 is 7
Notice that 7 = HCF(28,7) = HCF(119,28) = HCF(266,119) = HCF(651,266) = HCF(917,651) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 923 > 7, we apply the division lemma to 923 and 7, to get
923 = 7 x 131 + 6
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 6 and 7, to get
7 = 6 x 1 + 1
Step 3: 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 7 and 923 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(923,7) .
