HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 938, 681, 453 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 938, 681, 453 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 938, 681, 453 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 938, 681, 453 is 1.
HCF(938, 681, 453) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 938, 681, 453 is 1.
Step 1: Since 938 > 681, we apply the division lemma to 938 and 681, to get
938 = 681 x 1 + 257
Step 2: Since the reminder 681 ≠ 0, we apply division lemma to 257 and 681, to get
681 = 257 x 2 + 167
Step 3: We consider the new divisor 257 and the new remainder 167, and apply the division lemma to get
257 = 167 x 1 + 90
We consider the new divisor 167 and the new remainder 90,and apply the division lemma to get
167 = 90 x 1 + 77
We consider the new divisor 90 and the new remainder 77,and apply the division lemma to get
90 = 77 x 1 + 13
We consider the new divisor 77 and the new remainder 13,and apply the division lemma to get
77 = 13 x 5 + 12
We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get
13 = 12 x 1 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 938 and 681 is 1
Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(77,13) = HCF(90,77) = HCF(167,90) = HCF(257,167) = HCF(681,257) = HCF(938,681) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 453 > 1, we apply the division lemma to 453 and 1, to get
453 = 1 x 453 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 453 is 1
Notice that 1 = HCF(453,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
