HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 280, 225, 980 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 280, 225, 980 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 280, 225, 980 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, 225, 980 is 5.
HCF(280, 225, 980) = 5
HCF of 280, 225, 980 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, 225, 980 is 5.
Highest Common Factor of 280,225,980 is 5
Step 1: Since 280 > 225, we apply the division lemma to 280 and 225, to get
280 = 225 x 1 + 55
Step 2: Since the reminder 225 ≠ 0, we apply division lemma to 55 and 225, to get
225 = 55 x 4 + 5
Step 3: We consider the new divisor 55 and the new remainder 5, and apply the division lemma to get
55 = 5 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 280 and 225 is 5
Notice that 5 = HCF(55,5) = HCF(225,55) = HCF(280,225) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 980 > 5, we apply the division lemma to 980 and 5, to get
980 = 5 x 196 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 980 is 5
Notice that 5 = HCF(980,5) .
