HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 574, 995, 972 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 574, 995, 972 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 574, 995, 972 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 574, 995, 972 is 1.
HCF(574, 995, 972) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 574, 995, 972 is 1.
Step 1: Since 995 > 574, we apply the division lemma to 995 and 574, to get
995 = 574 x 1 + 421
Step 2: Since the reminder 574 ≠ 0, we apply division lemma to 421 and 574, to get
574 = 421 x 1 + 153
Step 3: We consider the new divisor 421 and the new remainder 153, and apply the division lemma to get
421 = 153 x 2 + 115
We consider the new divisor 153 and the new remainder 115,and apply the division lemma to get
153 = 115 x 1 + 38
We consider the new divisor 115 and the new remainder 38,and apply the division lemma to get
115 = 38 x 3 + 1
We consider the new divisor 38 and the new remainder 1,and apply the division lemma to get
38 = 1 x 38 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 574 and 995 is 1
Notice that 1 = HCF(38,1) = HCF(115,38) = HCF(153,115) = HCF(421,153) = HCF(574,421) = HCF(995,574) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 972 > 1, we apply the division lemma to 972 and 1, to get
972 = 1 x 972 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 972 is 1
Notice that 1 = HCF(972,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
