HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 280, 385 i.e. 35 the largest integer that leaves a remainder zero for all numbers.
HCF of 280, 385 is 35 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 280, 385 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 280, 385 is 35.
HCF(280, 385) = 35
HCF of 280, 385 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 280, 385 is 35.
Highest Common Factor of 280,385 is 35
Step 1: Since 385 > 280, we apply the division lemma to 385 and 280, to get
385 = 280 x 1 + 105
Step 2: Since the reminder 280 ≠ 0, we apply division lemma to 105 and 280, to get
280 = 105 x 2 + 70
Step 3: We consider the new divisor 105 and the new remainder 70, and apply the division lemma to get
105 = 70 x 1 + 35
We consider the new divisor 70 and the new remainder 35, and apply the division lemma to get
70 = 35 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 35, the HCF of 280 and 385 is 35
Notice that 35 = HCF(70,35) = HCF(105,70) = HCF(280,105) = HCF(385,280) .
