HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 779, 994, 47, 851 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 779, 994, 47, 851 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 779, 994, 47, 851 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 779, 994, 47, 851 is 1.
HCF(779, 994, 47, 851) = 1
HCF of 779, 994, 47, 851 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 779, 994, 47, 851 is 1.
Highest Common Factor of 779,994,47,851 is 1
Step 1: Since 994 > 779, we apply the division lemma to 994 and 779, to get
994 = 779 x 1 + 215
Step 2: Since the reminder 779 ≠ 0, we apply division lemma to 215 and 779, to get
779 = 215 x 3 + 134
Step 3: We consider the new divisor 215 and the new remainder 134, and apply the division lemma to get
215 = 134 x 1 + 81
We consider the new divisor 134 and the new remainder 81,and apply the division lemma to get
134 = 81 x 1 + 53
We consider the new divisor 81 and the new remainder 53,and apply the division lemma to get
81 = 53 x 1 + 28
We consider the new divisor 53 and the new remainder 28,and apply the division lemma to get
53 = 28 x 1 + 25
We consider the new divisor 28 and the new remainder 25,and apply the division lemma to get
28 = 25 x 1 + 3
We consider the new divisor 25 and the new remainder 3,and apply the division lemma to get
25 = 3 x 8 + 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 779 and 994 is 1
Notice that 1 = HCF(3,1) = HCF(25,3) = HCF(28,25) = HCF(53,28) = HCF(81,53) = HCF(134,81) = HCF(215,134) = HCF(779,215) = HCF(994,779) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 47 > 1, we apply the division lemma to 47 and 1, to get
47 = 1 x 47 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 47 is 1
Notice that 1 = HCF(47,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 851 > 1, we apply the division lemma to 851 and 1, to get
851 = 1 x 851 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 851 is 1
Notice that 1 = HCF(851,1) .
