HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 804, 970 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 804, 970 is 2 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 804, 970 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 804, 970 is 2.
HCF(804, 970) = 2
HCF of 804, 970 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 804, 970 is 2.
Highest Common Factor of 804,970 is 2
Step 1: Since 970 > 804, we apply the division lemma to 970 and 804, to get
970 = 804 x 1 + 166
Step 2: Since the reminder 804 ≠ 0, we apply division lemma to 166 and 804, to get
804 = 166 x 4 + 140
Step 3: We consider the new divisor 166 and the new remainder 140, and apply the division lemma to get
166 = 140 x 1 + 26
We consider the new divisor 140 and the new remainder 26,and apply the division lemma to get
140 = 26 x 5 + 10
We consider the new divisor 26 and the new remainder 10,and apply the division lemma to get
26 = 10 x 2 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 804 and 970 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(26,10) = HCF(140,26) = HCF(166,140) = HCF(804,166) = HCF(970,804) .
