HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 400, 912, 159, 311 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 400, 912, 159, 311 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 400, 912, 159, 311 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 400, 912, 159, 311 is 1.
HCF(400, 912, 159, 311) = 1
HCF of 400, 912, 159, 311 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 400, 912, 159, 311 is 1.
Highest Common Factor of 400,912,159,311 is 1
Step 1: Since 912 > 400, we apply the division lemma to 912 and 400, to get
912 = 400 x 2 + 112
Step 2: Since the reminder 400 ≠ 0, we apply division lemma to 112 and 400, to get
400 = 112 x 3 + 64
Step 3: We consider the new divisor 112 and the new remainder 64, and apply the division lemma to get
112 = 64 x 1 + 48
We consider the new divisor 64 and the new remainder 48,and apply the division lemma to get
64 = 48 x 1 + 16
We consider the new divisor 48 and the new remainder 16,and apply the division lemma to get
48 = 16 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 400 and 912 is 16
Notice that 16 = HCF(48,16) = HCF(64,48) = HCF(112,64) = HCF(400,112) = HCF(912,400) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 159 > 16, we apply the division lemma to 159 and 16, to get
159 = 16 x 9 + 15
Step 2: Since the reminder 16 ≠ 0, we apply division lemma to 15 and 16, to get
16 = 15 x 1 + 1
Step 3: We consider the new divisor 15 and the new remainder 1, and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 16 and 159 is 1
Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(159,16) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 311 > 1, we apply the division lemma to 311 and 1, to get
311 = 1 x 311 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 311 is 1
Notice that 1 = HCF(311,1) .
