HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 974, 842, 556, 814 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 974, 842, 556, 814 is 2 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, 842, 556, 814 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, 842, 556, 814 is 2.
HCF(974, 842, 556, 814) = 2
HCF of 974, 842, 556, 814 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 974, 842, 556, 814 is 2.
Highest Common Factor of 974,842,556,814 is 2
Step 1: Since 974 > 842, we apply the division lemma to 974 and 842, to get
974 = 842 x 1 + 132
Step 2: Since the reminder 842 ≠ 0, we apply division lemma to 132 and 842, to get
842 = 132 x 6 + 50
Step 3: We consider the new divisor 132 and the new remainder 50, and apply the division lemma to get
132 = 50 x 2 + 32
We consider the new divisor 50 and the new remainder 32,and apply the division lemma to get
50 = 32 x 1 + 18
We consider the new divisor 32 and the new remainder 18,and apply the division lemma to get
32 = 18 x 1 + 14
We consider the new divisor 18 and the new remainder 14,and apply the division lemma to get
18 = 14 x 1 + 4
We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get
14 = 4 x 3 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 974 and 842 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(32,18) = HCF(50,32) = HCF(132,50) = HCF(842,132) = HCF(974,842) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 556 > 2, we apply the division lemma to 556 and 2, to get
556 = 2 x 278 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 556 is 2
Notice that 2 = HCF(556,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 814 > 2, we apply the division lemma to 814 and 2, to get
814 = 2 x 407 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 814 is 2
Notice that 2 = HCF(814,2) .
