HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 957, 142, 553 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 957, 142, 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 957, 142, 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 957, 142, 553 is 1.
HCF(957, 142, 553) = 1
HCF of 957, 142, 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 957, 142, 553 is 1.
Highest Common Factor of 957,142,553 is 1
Step 1: Since 957 > 142, we apply the division lemma to 957 and 142, to get
957 = 142 x 6 + 105
Step 2: Since the reminder 142 ≠ 0, we apply division lemma to 105 and 142, to get
142 = 105 x 1 + 37
Step 3: We consider the new divisor 105 and the new remainder 37, and apply the division lemma to get
105 = 37 x 2 + 31
We consider the new divisor 37 and the new remainder 31,and apply the division lemma to get
37 = 31 x 1 + 6
We consider the new divisor 31 and the new remainder 6,and apply the division lemma to get
31 = 6 x 5 + 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 957 and 142 is 1
Notice that 1 = HCF(6,1) = HCF(31,6) = HCF(37,31) = HCF(105,37) = HCF(142,105) = HCF(957,142) .
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) .
