HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 456, 554, 971 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 456, 554, 971 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 456, 554, 971 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 456, 554, 971 is 1.
HCF(456, 554, 971) = 1
HCF of 456, 554, 971 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 456, 554, 971 is 1.
Highest Common Factor of 456,554,971 is 1
Step 1: Since 554 > 456, we apply the division lemma to 554 and 456, to get
554 = 456 x 1 + 98
Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 98 and 456, to get
456 = 98 x 4 + 64
Step 3: We consider the new divisor 98 and the new remainder 64, and apply the division lemma to get
98 = 64 x 1 + 34
We consider the new divisor 64 and the new remainder 34,and apply the division lemma to get
64 = 34 x 1 + 30
We consider the new divisor 34 and the new remainder 30,and apply the division lemma to get
34 = 30 x 1 + 4
We consider the new divisor 30 and the new remainder 4,and apply the division lemma to get
30 = 4 x 7 + 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 456 and 554 is 2
Notice that 2 = HCF(4,2) = HCF(30,4) = HCF(34,30) = HCF(64,34) = HCF(98,64) = HCF(456,98) = HCF(554,456) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 971 > 2, we apply the division lemma to 971 and 2, to get
971 = 2 x 485 + 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 971 is 1
Notice that 1 = HCF(2,1) = HCF(971,2) .
