HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 818, 249, 455, 137 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 818, 249, 455, 137 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 818, 249, 455, 137 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 818, 249, 455, 137 is 1.
HCF(818, 249, 455, 137) = 1
HCF of 818, 249, 455, 137 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 818, 249, 455, 137 is 1.
Highest Common Factor of 818,249,455,137 is 1
Step 1: Since 818 > 249, we apply the division lemma to 818 and 249, to get
818 = 249 x 3 + 71
Step 2: Since the reminder 249 ≠ 0, we apply division lemma to 71 and 249, to get
249 = 71 x 3 + 36
Step 3: We consider the new divisor 71 and the new remainder 36, and apply the division lemma to get
71 = 36 x 1 + 35
We consider the new divisor 36 and the new remainder 35,and apply the division lemma to get
36 = 35 x 1 + 1
We consider the new divisor 35 and the new remainder 1,and apply the division lemma to get
35 = 1 x 35 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 818 and 249 is 1
Notice that 1 = HCF(35,1) = HCF(36,35) = HCF(71,36) = HCF(249,71) = HCF(818,249) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 455 > 1, we apply the division lemma to 455 and 1, to get
455 = 1 x 455 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 455 is 1
Notice that 1 = HCF(455,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 137 > 1, we apply the division lemma to 137 and 1, to get
137 = 1 x 137 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 137 is 1
Notice that 1 = HCF(137,1) .
