HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 846, 520, 989 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 846, 520, 989 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 846, 520, 989 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 846, 520, 989 is 1.
HCF(846, 520, 989) = 1
HCF of 846, 520, 989 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 846, 520, 989 is 1.
Highest Common Factor of 846,520,989 is 1
Step 1: Since 846 > 520, we apply the division lemma to 846 and 520, to get
846 = 520 x 1 + 326
Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 326 and 520, to get
520 = 326 x 1 + 194
Step 3: We consider the new divisor 326 and the new remainder 194, and apply the division lemma to get
326 = 194 x 1 + 132
We consider the new divisor 194 and the new remainder 132,and apply the division lemma to get
194 = 132 x 1 + 62
We consider the new divisor 132 and the new remainder 62,and apply the division lemma to get
132 = 62 x 2 + 8
We consider the new divisor 62 and the new remainder 8,and apply the division lemma to get
62 = 8 x 7 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 846 and 520 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(62,8) = HCF(132,62) = HCF(194,132) = HCF(326,194) = HCF(520,326) = HCF(846,520) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 989 > 2, we apply the division lemma to 989 and 2, to get
989 = 2 x 494 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 989 is 1
Notice that 1 = HCF(2,1) = HCF(989,2) .
