HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 193, 717, 915 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 193, 717, 915 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 193, 717, 915 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 193, 717, 915 is 1.
HCF(193, 717, 915) = 1
HCF of 193, 717, 915 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 193, 717, 915 is 1.
Highest Common Factor of 193,717,915 is 1
Step 1: Since 717 > 193, we apply the division lemma to 717 and 193, to get
717 = 193 x 3 + 138
Step 2: Since the reminder 193 ≠ 0, we apply division lemma to 138 and 193, to get
193 = 138 x 1 + 55
Step 3: We consider the new divisor 138 and the new remainder 55, and apply the division lemma to get
138 = 55 x 2 + 28
We consider the new divisor 55 and the new remainder 28,and apply the division lemma to get
55 = 28 x 1 + 27
We consider the new divisor 28 and the new remainder 27,and apply the division lemma to get
28 = 27 x 1 + 1
We consider the new divisor 27 and the new remainder 1,and apply the division lemma to get
27 = 1 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 193 and 717 is 1
Notice that 1 = HCF(27,1) = HCF(28,27) = HCF(55,28) = HCF(138,55) = HCF(193,138) = HCF(717,193) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 915 > 1, we apply the division lemma to 915 and 1, to get
915 = 1 x 915 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 915 is 1
Notice that 1 = HCF(915,1) .
