HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 297, 2220 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 297, 2220 is 3 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 297, 2220 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 297, 2220 is 3.
HCF(297, 2220) = 3
HCF of 297, 2220 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 297, 2220 is 3.
Highest Common Factor of 297,2220 is 3
Step 1: Since 2220 > 297, we apply the division lemma to 2220 and 297, to get
2220 = 297 x 7 + 141
Step 2: Since the reminder 297 ≠ 0, we apply division lemma to 141 and 297, to get
297 = 141 x 2 + 15
Step 3: We consider the new divisor 141 and the new remainder 15, and apply the division lemma to get
141 = 15 x 9 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 297 and 2220 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(141,15) = HCF(297,141) = HCF(2220,297) .
