HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 901, 561, 484 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 901, 561, 484 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, 561, 484 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, 561, 484 is 1.
HCF(901, 561, 484) = 1
HCF of 901, 561, 484 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 901, 561, 484 is 1.
Highest Common Factor of 901,561,484 is 1
Step 1: Since 901 > 561, we apply the division lemma to 901 and 561, to get
901 = 561 x 1 + 340
Step 2: Since the reminder 561 ≠ 0, we apply division lemma to 340 and 561, to get
561 = 340 x 1 + 221
Step 3: We consider the new divisor 340 and the new remainder 221, and apply the division lemma to get
340 = 221 x 1 + 119
We consider the new divisor 221 and the new remainder 119,and apply the division lemma to get
221 = 119 x 1 + 102
We consider the new divisor 119 and the new remainder 102,and apply the division lemma to get
119 = 102 x 1 + 17
We consider the new divisor 102 and the new remainder 17,and apply the division lemma to get
102 = 17 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 901 and 561 is 17
Notice that 17 = HCF(102,17) = HCF(119,102) = HCF(221,119) = HCF(340,221) = HCF(561,340) = HCF(901,561) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 484 > 17, we apply the division lemma to 484 and 17, to get
484 = 17 x 28 + 8
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 8 and 17, to get
17 = 8 x 2 + 1
Step 3: We consider the new divisor 8 and the new remainder 1, and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 17 and 484 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(484,17) .
