HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 762, 972 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 438, 762, 972 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 438, 762, 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 438, 762, 972 is 6.
HCF(438, 762, 972) = 6
HCF of 438, 762, 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 438, 762, 972 is 6.
Highest Common Factor of 438,762,972 is 6
Step 1: Since 762 > 438, we apply the division lemma to 762 and 438, to get
762 = 438 x 1 + 324
Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 324 and 438, to get
438 = 324 x 1 + 114
Step 3: We consider the new divisor 324 and the new remainder 114, and apply the division lemma to get
324 = 114 x 2 + 96
We consider the new divisor 114 and the new remainder 96,and apply the division lemma to get
114 = 96 x 1 + 18
We consider the new divisor 96 and the new remainder 18,and apply the division lemma to get
96 = 18 x 5 + 6
We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get
18 = 6 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 438 and 762 is 6
Notice that 6 = HCF(18,6) = HCF(96,18) = HCF(114,96) = HCF(324,114) = HCF(438,324) = HCF(762,438) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 972 > 6, we apply the division lemma to 972 and 6, to get
972 = 6 x 162 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 6 and 972 is 6
Notice that 6 = HCF(972,6) .
