HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 860, 490, 28 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 860, 490, 28 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 860, 490, 28 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, 490, 28 is 2.
HCF(860, 490, 28) = 2
HCF of 860, 490, 28 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, 490, 28 is 2.
Highest Common Factor of 860,490,28 is 2
Step 1: Since 860 > 490, we apply the division lemma to 860 and 490, to get
860 = 490 x 1 + 370
Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 370 and 490, to get
490 = 370 x 1 + 120
Step 3: We consider the new divisor 370 and the new remainder 120, and apply the division lemma to get
370 = 120 x 3 + 10
We consider the new divisor 120 and the new remainder 10, and apply the division lemma to get
120 = 10 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 860 and 490 is 10
Notice that 10 = HCF(120,10) = HCF(370,120) = HCF(490,370) = HCF(860,490) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 28 > 10, we apply the division lemma to 28 and 10, to get
28 = 10 x 2 + 8
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 8 and 10, to get
10 = 8 x 1 + 2
Step 3: We consider the new divisor 8 and the new remainder 2, and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 28 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(28,10) .
