HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 799, 625, 694, 45 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 799, 625, 694, 45 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 799, 625, 694, 45 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 799, 625, 694, 45 is 1.
HCF(799, 625, 694, 45) = 1
HCF of 799, 625, 694, 45 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 799, 625, 694, 45 is 1.
Highest Common Factor of 799,625,694,45 is 1
Step 1: Since 799 > 625, we apply the division lemma to 799 and 625, to get
799 = 625 x 1 + 174
Step 2: Since the reminder 625 ≠ 0, we apply division lemma to 174 and 625, to get
625 = 174 x 3 + 103
Step 3: We consider the new divisor 174 and the new remainder 103, and apply the division lemma to get
174 = 103 x 1 + 71
We consider the new divisor 103 and the new remainder 71,and apply the division lemma to get
103 = 71 x 1 + 32
We consider the new divisor 71 and the new remainder 32,and apply the division lemma to get
71 = 32 x 2 + 7
We consider the new divisor 32 and the new remainder 7,and apply the division lemma to get
32 = 7 x 4 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 799 and 625 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(32,7) = HCF(71,32) = HCF(103,71) = HCF(174,103) = HCF(625,174) = HCF(799,625) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 694 > 1, we apply the division lemma to 694 and 1, to get
694 = 1 x 694 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 694 is 1
Notice that 1 = HCF(694,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 45 > 1, we apply the division lemma to 45 and 1, to get
45 = 1 x 45 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 45 is 1
Notice that 1 = HCF(45,1) .
