HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 98, 22, 64, 658 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 98, 22, 64, 658 is 2 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, 22, 64, 658 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, 22, 64, 658 is 2.
HCF(98, 22, 64, 658) = 2
HCF of 98, 22, 64, 658 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, 22, 64, 658 is 2.
Highest Common Factor of 98,22,64,658 is 2
Step 1: Since 98 > 22, we apply the division lemma to 98 and 22, to get
98 = 22 x 4 + 10
Step 2: Since the reminder 22 ≠ 0, we apply division lemma to 10 and 22, to get
22 = 10 x 2 + 2
Step 3: We consider the new divisor 10 and the new remainder 2, and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 98 and 22 is 2
Notice that 2 = HCF(10,2) = HCF(22,10) = HCF(98,22) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 64 > 2, we apply the division lemma to 64 and 2, to get
64 = 2 x 32 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 64 is 2
Notice that 2 = HCF(64,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 658 > 2, we apply the division lemma to 658 and 2, to get
658 = 2 x 329 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 658 is 2
Notice that 2 = HCF(658,2) .
