HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 629, 974 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 629, 974 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 629, 974 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 629, 974 is 1.
HCF(629, 974) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 629, 974 is 1.
Step 1: Since 974 > 629, we apply the division lemma to 974 and 629, to get
974 = 629 x 1 + 345
Step 2: Since the reminder 629 ≠ 0, we apply division lemma to 345 and 629, to get
629 = 345 x 1 + 284
Step 3: We consider the new divisor 345 and the new remainder 284, and apply the division lemma to get
345 = 284 x 1 + 61
We consider the new divisor 284 and the new remainder 61,and apply the division lemma to get
284 = 61 x 4 + 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 629 and 974 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(40,21) = HCF(61,40) = HCF(284,61) = HCF(345,284) = HCF(629,345) = HCF(974,629) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
