HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 270, 985 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 270, 985 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 270, 985 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 270, 985 is 5.
HCF(270, 985) = 5
HCF of 270, 985 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 270, 985 is 5.
Highest Common Factor of 270,985 is 5
Step 1: Since 985 > 270, we apply the division lemma to 985 and 270, to get
985 = 270 x 3 + 175
Step 2: Since the reminder 270 ≠ 0, we apply division lemma to 175 and 270, to get
270 = 175 x 1 + 95
Step 3: We consider the new divisor 175 and the new remainder 95, and apply the division lemma to get
175 = 95 x 1 + 80
We consider the new divisor 95 and the new remainder 80,and apply the division lemma to get
95 = 80 x 1 + 15
We consider the new divisor 80 and the new remainder 15,and apply the division lemma to get
80 = 15 x 5 + 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 270 and 985 is 5
Notice that 5 = HCF(15,5) = HCF(80,15) = HCF(95,80) = HCF(175,95) = HCF(270,175) = HCF(985,270) .
