HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 411, 690, 253 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 411, 690, 253 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 411, 690, 253 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 411, 690, 253 is 1.
HCF(411, 690, 253) = 1
HCF of 411, 690, 253 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 411, 690, 253 is 1.
Highest Common Factor of 411,690,253 is 1
Step 1: Since 690 > 411, we apply the division lemma to 690 and 411, to get
690 = 411 x 1 + 279
Step 2: Since the reminder 411 ≠ 0, we apply division lemma to 279 and 411, to get
411 = 279 x 1 + 132
Step 3: We consider the new divisor 279 and the new remainder 132, and apply the division lemma to get
279 = 132 x 2 + 15
We consider the new divisor 132 and the new remainder 15,and apply the division lemma to get
132 = 15 x 8 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 411 and 690 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(132,15) = HCF(279,132) = HCF(411,279) = HCF(690,411) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 253 > 3, we apply the division lemma to 253 and 3, to get
253 = 3 x 84 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 253 is 1
Notice that 1 = HCF(3,1) = HCF(253,3) .
