HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 919, 570, 197 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 919, 570, 197 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 919, 570, 197 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 919, 570, 197 is 1.
HCF(919, 570, 197) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 919, 570, 197 is 1.
Step 1: Since 919 > 570, we apply the division lemma to 919 and 570, to get
919 = 570 x 1 + 349
Step 2: Since the reminder 570 ≠ 0, we apply division lemma to 349 and 570, to get
570 = 349 x 1 + 221
Step 3: We consider the new divisor 349 and the new remainder 221, and apply the division lemma to get
349 = 221 x 1 + 128
We consider the new divisor 221 and the new remainder 128,and apply the division lemma to get
221 = 128 x 1 + 93
We consider the new divisor 128 and the new remainder 93,and apply the division lemma to get
128 = 93 x 1 + 35
We consider the new divisor 93 and the new remainder 35,and apply the division lemma to get
93 = 35 x 2 + 23
We consider the new divisor 35 and the new remainder 23,and apply the division lemma to get
35 = 23 x 1 + 12
We consider the new divisor 23 and the new remainder 12,and apply the division lemma to get
23 = 12 x 1 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 919 and 570 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(23,12) = HCF(35,23) = HCF(93,35) = HCF(128,93) = HCF(221,128) = HCF(349,221) = HCF(570,349) = HCF(919,570) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 197 > 1, we apply the division lemma to 197 and 1, to get
197 = 1 x 197 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 197 is 1
Notice that 1 = HCF(197,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
