HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 974, 381, 699 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 974, 381, 699 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, 381, 699 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, 381, 699 is 1.
HCF(974, 381, 699) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 974, 381, 699 is 1.
Step 1: Since 974 > 381, we apply the division lemma to 974 and 381, to get
974 = 381 x 2 + 212
Step 2: Since the reminder 381 ≠ 0, we apply division lemma to 212 and 381, to get
381 = 212 x 1 + 169
Step 3: We consider the new divisor 212 and the new remainder 169, and apply the division lemma to get
212 = 169 x 1 + 43
We consider the new divisor 169 and the new remainder 43,and apply the division lemma to get
169 = 43 x 3 + 40
We consider the new divisor 43 and the new remainder 40,and apply the division lemma to get
43 = 40 x 1 + 3
We consider the new divisor 40 and the new remainder 3,and apply the division lemma to get
40 = 3 x 13 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 974 and 381 is 1
Notice that 1 = HCF(3,1) = HCF(40,3) = HCF(43,40) = HCF(169,43) = HCF(212,169) = HCF(381,212) = HCF(974,381) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 699 > 1, we apply the division lemma to 699 and 1, to get
699 = 1 x 699 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 699 is 1
Notice that 1 = HCF(699,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
