HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 928, 665, 98 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 928, 665, 98 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 928, 665, 98 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 928, 665, 98 is 1.
HCF(928, 665, 98) = 1
HCF of 928, 665, 98 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 928, 665, 98 is 1.
Highest Common Factor of 928,665,98 is 1
Step 1: Since 928 > 665, we apply the division lemma to 928 and 665, to get
928 = 665 x 1 + 263
Step 2: Since the reminder 665 ≠ 0, we apply division lemma to 263 and 665, to get
665 = 263 x 2 + 139
Step 3: We consider the new divisor 263 and the new remainder 139, and apply the division lemma to get
263 = 139 x 1 + 124
We consider the new divisor 139 and the new remainder 124,and apply the division lemma to get
139 = 124 x 1 + 15
We consider the new divisor 124 and the new remainder 15,and apply the division lemma to get
124 = 15 x 8 + 4
We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get
15 = 4 x 3 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 928 and 665 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(124,15) = HCF(139,124) = HCF(263,139) = HCF(665,263) = HCF(928,665) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 98 > 1, we apply the division lemma to 98 and 1, to get
98 = 1 x 98 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 98 is 1
Notice that 1 = HCF(98,1) .
