HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 838, 987, 898 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 838, 987, 898 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 838, 987, 898 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 838, 987, 898 is 1.
HCF(838, 987, 898) = 1
HCF of 838, 987, 898 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 838, 987, 898 is 1.
Highest Common Factor of 838,987,898 is 1
Step 1: Since 987 > 838, we apply the division lemma to 987 and 838, to get
987 = 838 x 1 + 149
Step 2: Since the reminder 838 ≠ 0, we apply division lemma to 149 and 838, to get
838 = 149 x 5 + 93
Step 3: We consider the new divisor 149 and the new remainder 93, and apply the division lemma to get
149 = 93 x 1 + 56
We consider the new divisor 93 and the new remainder 56,and apply the division lemma to get
93 = 56 x 1 + 37
We consider the new divisor 56 and the new remainder 37,and apply the division lemma to get
56 = 37 x 1 + 19
We consider the new divisor 37 and the new remainder 19,and apply the division lemma to get
37 = 19 x 1 + 18
We consider the new divisor 19 and the new remainder 18,and apply the division lemma to get
19 = 18 x 1 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 838 and 987 is 1
Notice that 1 = HCF(18,1) = HCF(19,18) = HCF(37,19) = HCF(56,37) = HCF(93,56) = HCF(149,93) = HCF(838,149) = HCF(987,838) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 898 > 1, we apply the division lemma to 898 and 1, to get
898 = 1 x 898 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 898 is 1
Notice that 1 = HCF(898,1) .
