HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 504, 168, 972 i.e. 12 the largest integer that leaves a remainder zero for all numbers.
HCF of 504, 168, 972 is 12 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 504, 168, 972 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 504, 168, 972 is 12.
HCF(504, 168, 972) = 12
HCF of 504, 168, 972 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 504, 168, 972 is 12.
Highest Common Factor of 504,168,972 is 12
Step 1: Since 504 > 168, we apply the division lemma to 504 and 168, to get
504 = 168 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 168, the HCF of 504 and 168 is 168
Notice that 168 = HCF(504,168) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 972 > 168, we apply the division lemma to 972 and 168, to get
972 = 168 x 5 + 132
Step 2: Since the reminder 168 ≠ 0, we apply division lemma to 132 and 168, to get
168 = 132 x 1 + 36
Step 3: We consider the new divisor 132 and the new remainder 36, and apply the division lemma to get
132 = 36 x 3 + 24
We consider the new divisor 36 and the new remainder 24,and apply the division lemma to get
36 = 24 x 1 + 12
We consider the new divisor 24 and the new remainder 12,and apply the division lemma to get
24 = 12 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 168 and 972 is 12
Notice that 12 = HCF(24,12) = HCF(36,24) = HCF(132,36) = HCF(168,132) = HCF(972,168) .
