HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 879, 981, 67, 809 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 879, 981, 67, 809 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 879, 981, 67, 809 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 879, 981, 67, 809 is 1.
HCF(879, 981, 67, 809) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 879, 981, 67, 809 is 1.
Step 1: Since 981 > 879, we apply the division lemma to 981 and 879, to get
981 = 879 x 1 + 102
Step 2: Since the reminder 879 ≠ 0, we apply division lemma to 102 and 879, to get
879 = 102 x 8 + 63
Step 3: We consider the new divisor 102 and the new remainder 63, and apply the division lemma to get
102 = 63 x 1 + 39
We consider the new divisor 63 and the new remainder 39,and apply the division lemma to get
63 = 39 x 1 + 24
We consider the new divisor 39 and the new remainder 24,and apply the division lemma to get
39 = 24 x 1 + 15
We consider the new divisor 24 and the new remainder 15,and apply the division lemma to get
24 = 15 x 1 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 879 and 981 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(24,15) = HCF(39,24) = HCF(63,39) = HCF(102,63) = HCF(879,102) = HCF(981,879) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 67 > 3, we apply the division lemma to 67 and 3, to get
67 = 3 x 22 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 67 is 1
Notice that 1 = HCF(3,1) = HCF(67,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 809 > 1, we apply the division lemma to 809 and 1, to get
809 = 1 x 809 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 809 is 1
Notice that 1 = HCF(809,1) .
