HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 974, 729, 676 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 974, 729, 676 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 974, 729, 676 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 974, 729, 676 is 1.
HCF(974, 729, 676) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 974, 729, 676 is 1.
Step 1: Since 974 > 729, we apply the division lemma to 974 and 729, to get
974 = 729 x 1 + 245
Step 2: Since the reminder 729 ≠ 0, we apply division lemma to 245 and 729, to get
729 = 245 x 2 + 239
Step 3: We consider the new divisor 245 and the new remainder 239, and apply the division lemma to get
245 = 239 x 1 + 6
We consider the new divisor 239 and the new remainder 6,and apply the division lemma to get
239 = 6 x 39 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 974 and 729 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(239,6) = HCF(245,239) = HCF(729,245) = HCF(974,729) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 676 > 1, we apply the division lemma to 676 and 1, to get
676 = 1 x 676 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 676 is 1
Notice that 1 = HCF(676,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
