HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 424, 805, 85, 553 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 424, 805, 85, 553 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 424, 805, 85, 553 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 424, 805, 85, 553 is 1.
HCF(424, 805, 85, 553) = 1
HCF of 424, 805, 85, 553 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 424, 805, 85, 553 is 1.
Highest Common Factor of 424,805,85,553 is 1
Step 1: Since 805 > 424, we apply the division lemma to 805 and 424, to get
805 = 424 x 1 + 381
Step 2: Since the reminder 424 ≠ 0, we apply division lemma to 381 and 424, to get
424 = 381 x 1 + 43
Step 3: We consider the new divisor 381 and the new remainder 43, and apply the division lemma to get
381 = 43 x 8 + 37
We consider the new divisor 43 and the new remainder 37,and apply the division lemma to get
43 = 37 x 1 + 6
We consider the new divisor 37 and the new remainder 6,and apply the division lemma to get
37 = 6 x 6 + 1
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 424 and 805 is 1
Notice that 1 = HCF(6,1) = HCF(37,6) = HCF(43,37) = HCF(381,43) = HCF(424,381) = HCF(805,424) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 85 > 1, we apply the division lemma to 85 and 1, to get
85 = 1 x 85 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 85 is 1
Notice that 1 = HCF(85,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 553 > 1, we apply the division lemma to 553 and 1, to get
553 = 1 x 553 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 553 is 1
Notice that 1 = HCF(553,1) .
