HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 488, 961, 195, 91 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 488, 961, 195, 91 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 488, 961, 195, 91 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 488, 961, 195, 91 is 1.
HCF(488, 961, 195, 91) = 1
HCF of 488, 961, 195, 91 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 488, 961, 195, 91 is 1.
Highest Common Factor of 488,961,195,91 is 1
Step 1: Since 961 > 488, we apply the division lemma to 961 and 488, to get
961 = 488 x 1 + 473
Step 2: Since the reminder 488 ≠ 0, we apply division lemma to 473 and 488, to get
488 = 473 x 1 + 15
Step 3: We consider the new divisor 473 and the new remainder 15, and apply the division lemma to get
473 = 15 x 31 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 488 and 961 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(473,15) = HCF(488,473) = HCF(961,488) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 195 > 1, we apply the division lemma to 195 and 1, to get
195 = 1 x 195 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 195 is 1
Notice that 1 = HCF(195,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 91 > 1, we apply the division lemma to 91 and 1, to get
91 = 1 x 91 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 91 is 1
Notice that 1 = HCF(91,1) .
