HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 689, 467, 771, 878 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 689, 467, 771, 878 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 689, 467, 771, 878 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 689, 467, 771, 878 is 1.
HCF(689, 467, 771, 878) = 1
HCF of 689, 467, 771, 878 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 689, 467, 771, 878 is 1.
Highest Common Factor of 689,467,771,878 is 1
Step 1: Since 689 > 467, we apply the division lemma to 689 and 467, to get
689 = 467 x 1 + 222
Step 2: Since the reminder 467 ≠ 0, we apply division lemma to 222 and 467, to get
467 = 222 x 2 + 23
Step 3: We consider the new divisor 222 and the new remainder 23, and apply the division lemma to get
222 = 23 x 9 + 15
We consider the new divisor 23 and the new remainder 15,and apply the division lemma to get
23 = 15 x 1 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 689 and 467 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(23,15) = HCF(222,23) = HCF(467,222) = HCF(689,467) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 771 > 1, we apply the division lemma to 771 and 1, to get
771 = 1 x 771 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 771 is 1
Notice that 1 = HCF(771,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 878 > 1, we apply the division lemma to 878 and 1, to get
878 = 1 x 878 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 878 is 1
Notice that 1 = HCF(878,1) .
