HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 901, 521, 920 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 901, 521, 920 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 901, 521, 920 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 901, 521, 920 is 1.
HCF(901, 521, 920) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 901, 521, 920 is 1.
Step 1: Since 901 > 521, we apply the division lemma to 901 and 521, to get
901 = 521 x 1 + 380
Step 2: Since the reminder 521 ≠ 0, we apply division lemma to 380 and 521, to get
521 = 380 x 1 + 141
Step 3: We consider the new divisor 380 and the new remainder 141, and apply the division lemma to get
380 = 141 x 2 + 98
We consider the new divisor 141 and the new remainder 98,and apply the division lemma to get
141 = 98 x 1 + 43
We consider the new divisor 98 and the new remainder 43,and apply the division lemma to get
98 = 43 x 2 + 12
We consider the new divisor 43 and the new remainder 12,and apply the division lemma to get
43 = 12 x 3 + 7
We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get
12 = 7 x 1 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 901 and 521 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(43,12) = HCF(98,43) = HCF(141,98) = HCF(380,141) = HCF(521,380) = HCF(901,521) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 920 > 1, we apply the division lemma to 920 and 1, to get
920 = 1 x 920 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 920 is 1
Notice that 1 = HCF(920,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
