HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 838, 712, 917, 807 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 838, 712, 917, 807 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 838, 712, 917, 807 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 838, 712, 917, 807 is 1.
HCF(838, 712, 917, 807) = 1
HCF of 838, 712, 917, 807 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 838, 712, 917, 807 is 1.
Highest Common Factor of 838,712,917,807 is 1
Step 1: Since 838 > 712, we apply the division lemma to 838 and 712, to get
838 = 712 x 1 + 126
Step 2: Since the reminder 712 ≠ 0, we apply division lemma to 126 and 712, to get
712 = 126 x 5 + 82
Step 3: We consider the new divisor 126 and the new remainder 82, and apply the division lemma to get
126 = 82 x 1 + 44
We consider the new divisor 82 and the new remainder 44,and apply the division lemma to get
82 = 44 x 1 + 38
We consider the new divisor 44 and the new remainder 38,and apply the division lemma to get
44 = 38 x 1 + 6
We consider the new divisor 38 and the new remainder 6,and apply the division lemma to get
38 = 6 x 6 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 838 and 712 is 2
Notice that 2 = HCF(6,2) = HCF(38,6) = HCF(44,38) = HCF(82,44) = HCF(126,82) = HCF(712,126) = HCF(838,712) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 917 > 2, we apply the division lemma to 917 and 2, to get
917 = 2 x 458 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 917 is 1
Notice that 1 = HCF(2,1) = HCF(917,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 807 > 1, we apply the division lemma to 807 and 1, to get
807 = 1 x 807 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 807 is 1
Notice that 1 = HCF(807,1) .
