HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 860, 180 i.e. 20 the largest integer that leaves a remainder zero for all numbers.
HCF of 860, 180 is 20 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 860, 180 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 860, 180 is 20.
HCF(860, 180) = 20
HCF of 860, 180 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 860, 180 is 20.
Highest Common Factor of 860,180 is 20
Step 1: Since 860 > 180, we apply the division lemma to 860 and 180, to get
860 = 180 x 4 + 140
Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 140 and 180, to get
180 = 140 x 1 + 40
Step 3: We consider the new divisor 140 and the new remainder 40, and apply the division lemma to get
140 = 40 x 3 + 20
We consider the new divisor 40 and the new remainder 20, and apply the division lemma to get
40 = 20 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 860 and 180 is 20
Notice that 20 = HCF(40,20) = HCF(140,40) = HCF(180,140) = HCF(860,180) .
