HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7200, 4940 i.e. 20 the largest integer that leaves a remainder zero for all numbers.
HCF of 7200, 4940 is 20 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 7200, 4940 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 7200, 4940 is 20.
HCF(7200, 4940) = 20
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7200, 4940 is 20.
Step 1: Since 7200 > 4940, we apply the division lemma to 7200 and 4940, to get
7200 = 4940 x 1 + 2260
Step 2: Since the reminder 4940 ≠ 0, we apply division lemma to 2260 and 4940, to get
4940 = 2260 x 2 + 420
Step 3: We consider the new divisor 2260 and the new remainder 420, and apply the division lemma to get
2260 = 420 x 5 + 160
We consider the new divisor 420 and the new remainder 160,and apply the division lemma to get
420 = 160 x 2 + 100
We consider the new divisor 160 and the new remainder 100,and apply the division lemma to get
160 = 100 x 1 + 60
We consider the new divisor 100 and the new remainder 60,and apply the division lemma to get
100 = 60 x 1 + 40
We consider the new divisor 60 and the new remainder 40,and apply the division lemma to get
60 = 40 x 1 + 20
We consider the new divisor 40 and the new remainder 20,and apply the division lemma to get
40 = 20 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 7200 and 4940 is 20
Notice that 20 = HCF(40,20) = HCF(60,40) = HCF(100,60) = HCF(160,100) = HCF(420,160) = HCF(2260,420) = HCF(4940,2260) = HCF(7200,4940) .
Here are some samples of HCF using Euclid's Algorithm calculations.
