HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 676, 981, 410 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 676, 981, 410 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 676, 981, 410 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 676, 981, 410 is 1.
HCF(676, 981, 410) = 1
HCF of 676, 981, 410 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 676, 981, 410 is 1.
Highest Common Factor of 676,981,410 is 1
Step 1: Since 981 > 676, we apply the division lemma to 981 and 676, to get
981 = 676 x 1 + 305
Step 2: Since the reminder 676 ≠ 0, we apply division lemma to 305 and 676, to get
676 = 305 x 2 + 66
Step 3: We consider the new divisor 305 and the new remainder 66, and apply the division lemma to get
305 = 66 x 4 + 41
We consider the new divisor 66 and the new remainder 41,and apply the division lemma to get
66 = 41 x 1 + 25
We consider the new divisor 41 and the new remainder 25,and apply the division lemma to get
41 = 25 x 1 + 16
We consider the new divisor 25 and the new remainder 16,and apply the division lemma to get
25 = 16 x 1 + 9
We consider the new divisor 16 and the new remainder 9,and apply the division lemma to get
16 = 9 x 1 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 676 and 981 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(16,9) = HCF(25,16) = HCF(41,25) = HCF(66,41) = HCF(305,66) = HCF(676,305) = HCF(981,676) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 410 > 1, we apply the division lemma to 410 and 1, to get
410 = 1 x 410 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 410 is 1
Notice that 1 = HCF(410,1) .
