HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 156, 570, 954 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 156, 570, 954 is 6 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 156, 570, 954 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 156, 570, 954 is 6.
HCF(156, 570, 954) = 6
HCF of 156, 570, 954 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 156, 570, 954 is 6.
Highest Common Factor of 156,570,954 is 6
Step 1: Since 570 > 156, we apply the division lemma to 570 and 156, to get
570 = 156 x 3 + 102
Step 2: Since the reminder 156 ≠ 0, we apply division lemma to 102 and 156, to get
156 = 102 x 1 + 54
Step 3: We consider the new divisor 102 and the new remainder 54, and apply the division lemma to get
102 = 54 x 1 + 48
We consider the new divisor 54 and the new remainder 48,and apply the division lemma to get
54 = 48 x 1 + 6
We consider the new divisor 48 and the new remainder 6,and apply the division lemma to get
48 = 6 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 156 and 570 is 6
Notice that 6 = HCF(48,6) = HCF(54,48) = HCF(102,54) = HCF(156,102) = HCF(570,156) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 954 > 6, we apply the division lemma to 954 and 6, to get
954 = 6 x 159 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 6 and 954 is 6
Notice that 6 = HCF(954,6) .
