HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 638, 383, 532 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 638, 383, 532 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 638, 383, 532 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 638, 383, 532 is 1.
HCF(638, 383, 532) = 1
HCF of 638, 383, 532 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 638, 383, 532 is 1.
Highest Common Factor of 638,383,532 is 1
Step 1: Since 638 > 383, we apply the division lemma to 638 and 383, to get
638 = 383 x 1 + 255
Step 2: Since the reminder 383 ≠ 0, we apply division lemma to 255 and 383, to get
383 = 255 x 1 + 128
Step 3: We consider the new divisor 255 and the new remainder 128, and apply the division lemma to get
255 = 128 x 1 + 127
We consider the new divisor 128 and the new remainder 127,and apply the division lemma to get
128 = 127 x 1 + 1
We consider the new divisor 127 and the new remainder 1,and apply the division lemma to get
127 = 1 x 127 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 638 and 383 is 1
Notice that 1 = HCF(127,1) = HCF(128,127) = HCF(255,128) = HCF(383,255) = HCF(638,383) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 532 > 1, we apply the division lemma to 532 and 1, to get
532 = 1 x 532 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 532 is 1
Notice that 1 = HCF(532,1) .
