HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 931, 505, 553 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 931, 505, 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 931, 505, 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 931, 505, 553 is 1.
HCF(931, 505, 553) = 1
HCF of 931, 505, 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 931, 505, 553 is 1.
Highest Common Factor of 931,505,553 is 1
Step 1: Since 931 > 505, we apply the division lemma to 931 and 505, to get
931 = 505 x 1 + 426
Step 2: Since the reminder 505 ≠ 0, we apply division lemma to 426 and 505, to get
505 = 426 x 1 + 79
Step 3: We consider the new divisor 426 and the new remainder 79, and apply the division lemma to get
426 = 79 x 5 + 31
We consider the new divisor 79 and the new remainder 31,and apply the division lemma to get
79 = 31 x 2 + 17
We consider the new divisor 31 and the new remainder 17,and apply the division lemma to get
31 = 17 x 1 + 14
We consider the new divisor 17 and the new remainder 14,and apply the division lemma to get
17 = 14 x 1 + 3
We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get
14 = 3 x 4 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 931 and 505 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(17,14) = HCF(31,17) = HCF(79,31) = HCF(426,79) = HCF(505,426) = HCF(931,505) .
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) .
