HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1969, 1470 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1969, 1470 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 1969, 1470 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 1969, 1470 is 1.
HCF(1969, 1470) = 1
HCF of 1969, 1470 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1969, 1470 is 1.
Highest Common Factor of 1969,1470 is 1
Step 1: Since 1969 > 1470, we apply the division lemma to 1969 and 1470, to get
1969 = 1470 x 1 + 499
Step 2: Since the reminder 1470 ≠ 0, we apply division lemma to 499 and 1470, to get
1470 = 499 x 2 + 472
Step 3: We consider the new divisor 499 and the new remainder 472, and apply the division lemma to get
499 = 472 x 1 + 27
We consider the new divisor 472 and the new remainder 27,and apply the division lemma to get
472 = 27 x 17 + 13
We consider the new divisor 27 and the new remainder 13,and apply the division lemma to get
27 = 13 x 2 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1969 and 1470 is 1
Notice that 1 = HCF(13,1) = HCF(27,13) = HCF(472,27) = HCF(499,472) = HCF(1470,499) = HCF(1969,1470) .
