HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 557, 98 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 557, 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 557, 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 557, 98 is 1.
HCF(557, 98) = 1
HCF of 557, 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 557, 98 is 1.
Highest Common Factor of 557,98 is 1
Step 1: Since 557 > 98, we apply the division lemma to 557 and 98, to get
557 = 98 x 5 + 67
Step 2: Since the reminder 98 ≠ 0, we apply division lemma to 67 and 98, to get
98 = 67 x 1 + 31
Step 3: We consider the new divisor 67 and the new remainder 31, and apply the division lemma to get
67 = 31 x 2 + 5
We consider the new divisor 31 and the new remainder 5,and apply the division lemma to get
31 = 5 x 6 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 557 and 98 is 1
Notice that 1 = HCF(5,1) = HCF(31,5) = HCF(67,31) = HCF(98,67) = HCF(557,98) .
