HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 400, 249, 406, 108 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 400, 249, 406, 108 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, 249, 406, 108 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, 249, 406, 108 is 1.
HCF(400, 249, 406, 108) = 1
HCF of 400, 249, 406, 108 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, 249, 406, 108 is 1.
Highest Common Factor of 400,249,406,108 is 1
Step 1: Since 400 > 249, we apply the division lemma to 400 and 249, to get
400 = 249 x 1 + 151
Step 2: Since the reminder 249 ≠ 0, we apply division lemma to 151 and 249, to get
249 = 151 x 1 + 98
Step 3: We consider the new divisor 151 and the new remainder 98, and apply the division lemma to get
151 = 98 x 1 + 53
We consider the new divisor 98 and the new remainder 53,and apply the division lemma to get
98 = 53 x 1 + 45
We consider the new divisor 53 and the new remainder 45,and apply the division lemma to get
53 = 45 x 1 + 8
We consider the new divisor 45 and the new remainder 8,and apply the division lemma to get
45 = 8 x 5 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 249 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(45,8) = HCF(53,45) = HCF(98,53) = HCF(151,98) = HCF(249,151) = HCF(400,249) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 406 > 1, we apply the division lemma to 406 and 1, to get
406 = 1 x 406 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 406 is 1
Notice that 1 = HCF(406,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 108 > 1, we apply the division lemma to 108 and 1, to get
108 = 1 x 108 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 108 is 1
Notice that 1 = HCF(108,1) .
