HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 677, 261, 994, 821 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 677, 261, 994, 821 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 677, 261, 994, 821 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 677, 261, 994, 821 is 1.
HCF(677, 261, 994, 821) = 1
HCF of 677, 261, 994, 821 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 677, 261, 994, 821 is 1.
Highest Common Factor of 677,261,994,821 is 1
Step 1: Since 677 > 261, we apply the division lemma to 677 and 261, to get
677 = 261 x 2 + 155
Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 155 and 261, to get
261 = 155 x 1 + 106
Step 3: We consider the new divisor 155 and the new remainder 106, and apply the division lemma to get
155 = 106 x 1 + 49
We consider the new divisor 106 and the new remainder 49,and apply the division lemma to get
106 = 49 x 2 + 8
We consider the new divisor 49 and the new remainder 8,and apply the division lemma to get
49 = 8 x 6 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 677 and 261 is 1
Notice that 1 = HCF(8,1) = HCF(49,8) = HCF(106,49) = HCF(155,106) = HCF(261,155) = HCF(677,261) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 994 > 1, we apply the division lemma to 994 and 1, to get
994 = 1 x 994 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 994 is 1
Notice that 1 = HCF(994,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 821 > 1, we apply the division lemma to 821 and 1, to get
821 = 1 x 821 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 821 is 1
Notice that 1 = HCF(821,1) .
