HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 98, 65, 34, 154 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 98, 65, 34, 154 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 98, 65, 34, 154 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 98, 65, 34, 154 is 1.
HCF(98, 65, 34, 154) = 1
HCF of 98, 65, 34, 154 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 98, 65, 34, 154 is 1.
Highest Common Factor of 98,65,34,154 is 1
Step 1: Since 98 > 65, we apply the division lemma to 98 and 65, to get
98 = 65 x 1 + 33
Step 2: Since the reminder 65 ≠ 0, we apply division lemma to 33 and 65, to get
65 = 33 x 1 + 32
Step 3: We consider the new divisor 33 and the new remainder 32, and apply the division lemma to get
33 = 32 x 1 + 1
We consider the new divisor 32 and the new remainder 1, and apply the division lemma to get
32 = 1 x 32 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 98 and 65 is 1
Notice that 1 = HCF(32,1) = HCF(33,32) = HCF(65,33) = HCF(98,65) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 34 > 1, we apply the division lemma to 34 and 1, to get
34 = 1 x 34 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 34 is 1
Notice that 1 = HCF(34,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 154 > 1, we apply the division lemma to 154 and 1, to get
154 = 1 x 154 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 154 is 1
Notice that 1 = HCF(154,1) .
