HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 915, 792, 171, 76 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 915, 792, 171, 76 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 915, 792, 171, 76 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 915, 792, 171, 76 is 1.
HCF(915, 792, 171, 76) = 1
HCF of 915, 792, 171, 76 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 915, 792, 171, 76 is 1.
Highest Common Factor of 915,792,171,76 is 1
Step 1: Since 915 > 792, we apply the division lemma to 915 and 792, to get
915 = 792 x 1 + 123
Step 2: Since the reminder 792 ≠ 0, we apply division lemma to 123 and 792, to get
792 = 123 x 6 + 54
Step 3: We consider the new divisor 123 and the new remainder 54, and apply the division lemma to get
123 = 54 x 2 + 15
We consider the new divisor 54 and the new remainder 15,and apply the division lemma to get
54 = 15 x 3 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 915 and 792 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(54,15) = HCF(123,54) = HCF(792,123) = HCF(915,792) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 171 > 3, we apply the division lemma to 171 and 3, to get
171 = 3 x 57 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 171 is 3
Notice that 3 = HCF(171,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 76 > 3, we apply the division lemma to 76 and 3, to get
76 = 3 x 25 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 76 is 1
Notice that 1 = HCF(3,1) = HCF(76,3) .
