HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 985, 6125 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 985, 6125 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 985, 6125 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 985, 6125 is 5.
HCF(985, 6125) = 5
HCF of 985, 6125 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 985, 6125 is 5.
Highest Common Factor of 985,6125 is 5
Step 1: Since 6125 > 985, we apply the division lemma to 6125 and 985, to get
6125 = 985 x 6 + 215
Step 2: Since the reminder 985 ≠ 0, we apply division lemma to 215 and 985, to get
985 = 215 x 4 + 125
Step 3: We consider the new divisor 215 and the new remainder 125, and apply the division lemma to get
215 = 125 x 1 + 90
We consider the new divisor 125 and the new remainder 90,and apply the division lemma to get
125 = 90 x 1 + 35
We consider the new divisor 90 and the new remainder 35,and apply the division lemma to get
90 = 35 x 2 + 20
We consider the new divisor 35 and the new remainder 20,and apply the division lemma to get
35 = 20 x 1 + 15
We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get
20 = 15 x 1 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 985 and 6125 is 5
Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(35,20) = HCF(90,35) = HCF(125,90) = HCF(215,125) = HCF(985,215) = HCF(6125,985) .
