HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 400, 153, 31 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 400, 153, 31 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, 153, 31 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, 153, 31 is 1.
HCF(400, 153, 31) = 1
HCF of 400, 153, 31 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, 153, 31 is 1.
Highest Common Factor of 400,153,31 is 1
Step 1: Since 400 > 153, we apply the division lemma to 400 and 153, to get
400 = 153 x 2 + 94
Step 2: Since the reminder 153 ≠ 0, we apply division lemma to 94 and 153, to get
153 = 94 x 1 + 59
Step 3: We consider the new divisor 94 and the new remainder 59, and apply the division lemma to get
94 = 59 x 1 + 35
We consider the new divisor 59 and the new remainder 35,and apply the division lemma to get
59 = 35 x 1 + 24
We consider the new divisor 35 and the new remainder 24,and apply the division lemma to get
35 = 24 x 1 + 11
We consider the new divisor 24 and the new remainder 11,and apply the division lemma to get
24 = 11 x 2 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 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 400 and 153 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(24,11) = HCF(35,24) = HCF(59,35) = HCF(94,59) = HCF(153,94) = HCF(400,153) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 31 > 1, we apply the division lemma to 31 and 1, to get
31 = 1 x 31 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 31 is 1
Notice that 1 = HCF(31,1) .
