HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 1531 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 1531 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 870, 1531 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 870, 1531 is 1.
HCF(870, 1531) = 1
HCF of 870, 1531 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 1531 is 1.
Highest Common Factor of 870,1531 is 1
Step 1: Since 1531 > 870, we apply the division lemma to 1531 and 870, to get
1531 = 870 x 1 + 661
Step 2: Since the reminder 870 ≠ 0, we apply division lemma to 661 and 870, to get
870 = 661 x 1 + 209
Step 3: We consider the new divisor 661 and the new remainder 209, and apply the division lemma to get
661 = 209 x 3 + 34
We consider the new divisor 209 and the new remainder 34,and apply the division lemma to get
209 = 34 x 6 + 5
We consider the new divisor 34 and the new remainder 5,and apply the division lemma to get
34 = 5 x 6 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 870 and 1531 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(34,5) = HCF(209,34) = HCF(661,209) = HCF(870,661) = HCF(1531,870) .
