HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 860, 700, 65 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 860, 700, 65 is 5 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, 700, 65 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, 700, 65 is 5.
HCF(860, 700, 65) = 5
HCF of 860, 700, 65 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, 700, 65 is 5.
Highest Common Factor of 860,700,65 is 5
Step 1: Since 860 > 700, we apply the division lemma to 860 and 700, to get
860 = 700 x 1 + 160
Step 2: Since the reminder 700 ≠ 0, we apply division lemma to 160 and 700, to get
700 = 160 x 4 + 60
Step 3: We consider the new divisor 160 and the new remainder 60, and apply the division lemma to get
160 = 60 x 2 + 40
We consider the new divisor 60 and the new remainder 40,and apply the division lemma to get
60 = 40 x 1 + 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 700 is 20
Notice that 20 = HCF(40,20) = HCF(60,40) = HCF(160,60) = HCF(700,160) = HCF(860,700) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 65 > 20, we apply the division lemma to 65 and 20, to get
65 = 20 x 3 + 5
Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 5 and 20, to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 20 and 65 is 5
Notice that 5 = HCF(20,5) = HCF(65,20) .
