HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 842, 908, 955 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 842, 908, 955 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 842, 908, 955 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 842, 908, 955 is 1.
HCF(842, 908, 955) = 1
HCF of 842, 908, 955 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 842, 908, 955 is 1.
Highest Common Factor of 842,908,955 is 1
Step 1: Since 908 > 842, we apply the division lemma to 908 and 842, to get
908 = 842 x 1 + 66
Step 2: Since the reminder 842 ≠ 0, we apply division lemma to 66 and 842, to get
842 = 66 x 12 + 50
Step 3: We consider the new divisor 66 and the new remainder 50, and apply the division lemma to get
66 = 50 x 1 + 16
We consider the new divisor 50 and the new remainder 16,and apply the division lemma to get
50 = 16 x 3 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 842 and 908 is 2
Notice that 2 = HCF(16,2) = HCF(50,16) = HCF(66,50) = HCF(842,66) = HCF(908,842) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 955 > 2, we apply the division lemma to 955 and 2, to get
955 = 2 x 477 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 955 is 1
Notice that 1 = HCF(2,1) = HCF(955,2) .
