HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 970, 386, 555 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 970, 386, 555 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 970, 386, 555 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 970, 386, 555 is 1.
HCF(970, 386, 555) = 1
HCF of 970, 386, 555 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 970, 386, 555 is 1.
Highest Common Factor of 970,386,555 is 1
Step 1: Since 970 > 386, we apply the division lemma to 970 and 386, to get
970 = 386 x 2 + 198
Step 2: Since the reminder 386 ≠ 0, we apply division lemma to 198 and 386, to get
386 = 198 x 1 + 188
Step 3: We consider the new divisor 198 and the new remainder 188, and apply the division lemma to get
198 = 188 x 1 + 10
We consider the new divisor 188 and the new remainder 10,and apply the division lemma to get
188 = 10 x 18 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 970 and 386 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(188,10) = HCF(198,188) = HCF(386,198) = HCF(970,386) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 555 > 2, we apply the division lemma to 555 and 2, to get
555 = 2 x 277 + 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 555 is 1
Notice that 1 = HCF(2,1) = HCF(555,2) .
