HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 422, 993, 581, 560 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 422, 993, 581, 560 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 422, 993, 581, 560 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 422, 993, 581, 560 is 1.
HCF(422, 993, 581, 560) = 1
HCF of 422, 993, 581, 560 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 422, 993, 581, 560 is 1.
Highest Common Factor of 422,993,581,560 is 1
Step 1: Since 993 > 422, we apply the division lemma to 993 and 422, to get
993 = 422 x 2 + 149
Step 2: Since the reminder 422 ≠ 0, we apply division lemma to 149 and 422, to get
422 = 149 x 2 + 124
Step 3: We consider the new divisor 149 and the new remainder 124, and apply the division lemma to get
149 = 124 x 1 + 25
We consider the new divisor 124 and the new remainder 25,and apply the division lemma to get
124 = 25 x 4 + 24
We consider the new divisor 25 and the new remainder 24,and apply the division lemma to get
25 = 24 x 1 + 1
We consider the new divisor 24 and the new remainder 1,and apply the division lemma to get
24 = 1 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 422 and 993 is 1
Notice that 1 = HCF(24,1) = HCF(25,24) = HCF(124,25) = HCF(149,124) = HCF(422,149) = HCF(993,422) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 581 > 1, we apply the division lemma to 581 and 1, to get
581 = 1 x 581 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 581 is 1
Notice that 1 = HCF(581,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 560 > 1, we apply the division lemma to 560 and 1, to get
560 = 1 x 560 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 560 is 1
Notice that 1 = HCF(560,1) .
