HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 705, 973, 677 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 705, 973, 677 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 705, 973, 677 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 705, 973, 677 is 1.
HCF(705, 973, 677) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 705, 973, 677 is 1.
Step 1: Since 973 > 705, we apply the division lemma to 973 and 705, to get
973 = 705 x 1 + 268
Step 2: Since the reminder 705 ≠ 0, we apply division lemma to 268 and 705, to get
705 = 268 x 2 + 169
Step 3: We consider the new divisor 268 and the new remainder 169, and apply the division lemma to get
268 = 169 x 1 + 99
We consider the new divisor 169 and the new remainder 99,and apply the division lemma to get
169 = 99 x 1 + 70
We consider the new divisor 99 and the new remainder 70,and apply the division lemma to get
99 = 70 x 1 + 29
We consider the new divisor 70 and the new remainder 29,and apply the division lemma to get
70 = 29 x 2 + 12
We consider the new divisor 29 and the new remainder 12,and apply the division lemma to get
29 = 12 x 2 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 705 and 973 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(29,12) = HCF(70,29) = HCF(99,70) = HCF(169,99) = HCF(268,169) = HCF(705,268) = HCF(973,705) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 677 > 1, we apply the division lemma to 677 and 1, to get
677 = 1 x 677 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 677 is 1
Notice that 1 = HCF(677,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
