HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 774, 1411 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 774, 1411 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 774, 1411 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 774, 1411 is 1.
HCF(774, 1411) = 1
HCF of 774, 1411 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 774, 1411 is 1.
Highest Common Factor of 774,1411 is 1
Step 1: Since 1411 > 774, we apply the division lemma to 1411 and 774, to get
1411 = 774 x 1 + 637
Step 2: Since the reminder 774 ≠ 0, we apply division lemma to 637 and 774, to get
774 = 637 x 1 + 137
Step 3: We consider the new divisor 637 and the new remainder 137, and apply the division lemma to get
637 = 137 x 4 + 89
We consider the new divisor 137 and the new remainder 89,and apply the division lemma to get
137 = 89 x 1 + 48
We consider the new divisor 89 and the new remainder 48,and apply the division lemma to get
89 = 48 x 1 + 41
We consider the new divisor 48 and the new remainder 41,and apply the division lemma to get
48 = 41 x 1 + 7
We consider the new divisor 41 and the new remainder 7,and apply the division lemma to get
41 = 7 x 5 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 774 and 1411 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(41,7) = HCF(48,41) = HCF(89,48) = HCF(137,89) = HCF(637,137) = HCF(774,637) = HCF(1411,774) .
