HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 602, 993, 83 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 497, 602, 993, 83 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 497, 602, 993, 83 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 497, 602, 993, 83 is 1.
HCF(497, 602, 993, 83) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 497, 602, 993, 83 is 1.
Step 1: Since 602 > 497, we apply the division lemma to 602 and 497, to get
602 = 497 x 1 + 105
Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 105 and 497, to get
497 = 105 x 4 + 77
Step 3: We consider the new divisor 105 and the new remainder 77, and apply the division lemma to get
105 = 77 x 1 + 28
We consider the new divisor 77 and the new remainder 28,and apply the division lemma to get
77 = 28 x 2 + 21
We consider the new divisor 28 and the new remainder 21,and apply the division lemma to get
28 = 21 x 1 + 7
We consider the new divisor 21 and the new remainder 7,and apply the division lemma to get
21 = 7 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 497 and 602 is 7
Notice that 7 = HCF(21,7) = HCF(28,21) = HCF(77,28) = HCF(105,77) = HCF(497,105) = HCF(602,497) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 993 > 7, we apply the division lemma to 993 and 7, to get
993 = 7 x 141 + 6
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 6 and 7, to get
7 = 6 x 1 + 1
Step 3: We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 993 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(993,7) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 83 > 1, we apply the division lemma to 83 and 1, to get
83 = 1 x 83 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 83 is 1
Notice that 1 = HCF(83,1) .
