HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 629, 904, 767 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 629, 904, 767 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 629, 904, 767 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 629, 904, 767 is 1.
HCF(629, 904, 767) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 629, 904, 767 is 1.
Step 1: Since 904 > 629, we apply the division lemma to 904 and 629, to get
904 = 629 x 1 + 275
Step 2: Since the reminder 629 ≠ 0, we apply division lemma to 275 and 629, to get
629 = 275 x 2 + 79
Step 3: We consider the new divisor 275 and the new remainder 79, and apply the division lemma to get
275 = 79 x 3 + 38
We consider the new divisor 79 and the new remainder 38,and apply the division lemma to get
79 = 38 x 2 + 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 629 and 904 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(38,3) = HCF(79,38) = HCF(275,79) = HCF(629,275) = HCF(904,629) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 767 > 1, we apply the division lemma to 767 and 1, to get
767 = 1 x 767 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 767 is 1
Notice that 1 = HCF(767,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
