HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 916, 717, 139 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 916, 717, 139 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 916, 717, 139 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 916, 717, 139 is 1.
HCF(916, 717, 139) = 1
HCF of 916, 717, 139 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 916, 717, 139 is 1.
Highest Common Factor of 916,717,139 is 1
Step 1: Since 916 > 717, we apply the division lemma to 916 and 717, to get
916 = 717 x 1 + 199
Step 2: Since the reminder 717 ≠ 0, we apply division lemma to 199 and 717, to get
717 = 199 x 3 + 120
Step 3: We consider the new divisor 199 and the new remainder 120, and apply the division lemma to get
199 = 120 x 1 + 79
We consider the new divisor 120 and the new remainder 79,and apply the division lemma to get
120 = 79 x 1 + 41
We consider the new divisor 79 and the new remainder 41,and apply the division lemma to get
79 = 41 x 1 + 38
We consider the new divisor 41 and the new remainder 38,and apply the division lemma to get
41 = 38 x 1 + 3
We consider the new divisor 38 and the new remainder 3,and apply the division lemma to get
38 = 3 x 12 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 916 and 717 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(38,3) = HCF(41,38) = HCF(79,41) = HCF(120,79) = HCF(199,120) = HCF(717,199) = HCF(916,717) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 139 > 1, we apply the division lemma to 139 and 1, to get
139 = 1 x 139 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 139 is 1
Notice that 1 = HCF(139,1) .
