HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 493, 893, 155 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 493, 893, 155 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 493, 893, 155 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 493, 893, 155 is 1.
HCF(493, 893, 155) = 1
HCF of 493, 893, 155 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 493, 893, 155 is 1.
Highest Common Factor of 493,893,155 is 1
Step 1: Since 893 > 493, we apply the division lemma to 893 and 493, to get
893 = 493 x 1 + 400
Step 2: Since the reminder 493 ≠ 0, we apply division lemma to 400 and 493, to get
493 = 400 x 1 + 93
Step 3: We consider the new divisor 400 and the new remainder 93, and apply the division lemma to get
400 = 93 x 4 + 28
We consider the new divisor 93 and the new remainder 28,and apply the division lemma to get
93 = 28 x 3 + 9
We consider the new divisor 28 and the new remainder 9,and apply the division lemma to get
28 = 9 x 3 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 493 and 893 is 1
Notice that 1 = HCF(9,1) = HCF(28,9) = HCF(93,28) = HCF(400,93) = HCF(493,400) = HCF(893,493) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 155 > 1, we apply the division lemma to 155 and 1, to get
155 = 1 x 155 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 155 is 1
Notice that 1 = HCF(155,1) .
