HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 625, 987, 843, 553 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 625, 987, 843, 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 625, 987, 843, 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 625, 987, 843, 553 is 1.
HCF(625, 987, 843, 553) = 1
HCF of 625, 987, 843, 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 625, 987, 843, 553 is 1.
Highest Common Factor of 625,987,843,553 is 1
Step 1: Since 987 > 625, we apply the division lemma to 987 and 625, to get
987 = 625 x 1 + 362
Step 2: Since the reminder 625 ≠ 0, we apply division lemma to 362 and 625, to get
625 = 362 x 1 + 263
Step 3: We consider the new divisor 362 and the new remainder 263, and apply the division lemma to get
362 = 263 x 1 + 99
We consider the new divisor 263 and the new remainder 99,and apply the division lemma to get
263 = 99 x 2 + 65
We consider the new divisor 99 and the new remainder 65,and apply the division lemma to get
99 = 65 x 1 + 34
We consider the new divisor 65 and the new remainder 34,and apply the division lemma to get
65 = 34 x 1 + 31
We consider the new divisor 34 and the new remainder 31,and apply the division lemma to get
34 = 31 x 1 + 3
We consider the new divisor 31 and the new remainder 3,and apply the division lemma to get
31 = 3 x 10 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 625 and 987 is 1
Notice that 1 = HCF(3,1) = HCF(31,3) = HCF(34,31) = HCF(65,34) = HCF(99,65) = HCF(263,99) = HCF(362,263) = HCF(625,362) = HCF(987,625) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 843 > 1, we apply the division lemma to 843 and 1, to get
843 = 1 x 843 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 843 is 1
Notice that 1 = HCF(843,1) .
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) .
