HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 985, 6685 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 985, 6685 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, 6685 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, 6685 is 5.
HCF(985, 6685) = 5
HCF of 985, 6685 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, 6685 is 5.
Highest Common Factor of 985,6685 is 5
Step 1: Since 6685 > 985, we apply the division lemma to 6685 and 985, to get
6685 = 985 x 6 + 775
Step 2: Since the reminder 985 ≠ 0, we apply division lemma to 775 and 985, to get
985 = 775 x 1 + 210
Step 3: We consider the new divisor 775 and the new remainder 210, and apply the division lemma to get
775 = 210 x 3 + 145
We consider the new divisor 210 and the new remainder 145,and apply the division lemma to get
210 = 145 x 1 + 65
We consider the new divisor 145 and the new remainder 65,and apply the division lemma to get
145 = 65 x 2 + 15
We consider the new divisor 65 and the new remainder 15,and apply the division lemma to get
65 = 15 x 4 + 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 6685 is 5
Notice that 5 = HCF(15,5) = HCF(65,15) = HCF(145,65) = HCF(210,145) = HCF(775,210) = HCF(985,775) = HCF(6685,985) .
