HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2947, 1504 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 2947, 1504 is 1 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 2947, 1504 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 2947, 1504 is 1.
HCF(2947, 1504) = 1
HCF of 2947, 1504 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2947, 1504 is 1.
Highest Common Factor of 2947,1504 is 1
Step 1: Since 2947 > 1504, we apply the division lemma to 2947 and 1504, to get
2947 = 1504 x 1 + 1443
Step 2: Since the reminder 1504 ≠ 0, we apply division lemma to 1443 and 1504, to get
1504 = 1443 x 1 + 61
Step 3: We consider the new divisor 1443 and the new remainder 61, and apply the division lemma to get
1443 = 61 x 23 + 40
We consider the new divisor 61 and the new remainder 40,and apply the division lemma to get
61 = 40 x 1 + 21
We consider the new divisor 40 and the new remainder 21,and apply the division lemma to get
40 = 21 x 1 + 19
We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get
21 = 19 x 1 + 2
We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get
19 = 2 x 9 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2947 and 1504 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(40,21) = HCF(61,40) = HCF(1443,61) = HCF(1504,1443) = HCF(2947,1504) .
