HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 98, 58, 912, 615 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 98, 58, 912, 615 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, 58, 912, 615 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, 58, 912, 615 is 1.
HCF(98, 58, 912, 615) = 1
HCF of 98, 58, 912, 615 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, 58, 912, 615 is 1.
Highest Common Factor of 98,58,912,615 is 1
Step 1: Since 98 > 58, we apply the division lemma to 98 and 58, to get
98 = 58 x 1 + 40
Step 2: Since the reminder 58 ≠ 0, we apply division lemma to 40 and 58, to get
58 = 40 x 1 + 18
Step 3: We consider the new divisor 40 and the new remainder 18, and apply the division lemma to get
40 = 18 x 2 + 4
We consider the new divisor 18 and the new remainder 4,and apply the division lemma to get
18 = 4 x 4 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 98 and 58 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(40,18) = HCF(58,40) = HCF(98,58) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 912 > 2, we apply the division lemma to 912 and 2, to get
912 = 2 x 456 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 912 is 2
Notice that 2 = HCF(912,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 615 > 2, we apply the division lemma to 615 and 2, to get
615 = 2 x 307 + 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 615 is 1
Notice that 1 = HCF(2,1) = HCF(615,2) .
