HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 868, 945, 672 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 868, 945, 672 is 7 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 868, 945, 672 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 868, 945, 672 is 7.
HCF(868, 945, 672) = 7
HCF of 868, 945, 672 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 868, 945, 672 is 7.
Highest Common Factor of 868,945,672 is 7
Step 1: Since 945 > 868, we apply the division lemma to 945 and 868, to get
945 = 868 x 1 + 77
Step 2: Since the reminder 868 ≠ 0, we apply division lemma to 77 and 868, to get
868 = 77 x 11 + 21
Step 3: We consider the new divisor 77 and the new remainder 21, and apply the division lemma to get
77 = 21 x 3 + 14
We consider the new divisor 21 and the new remainder 14,and apply the division lemma to get
21 = 14 x 1 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 868 and 945 is 7
Notice that 7 = HCF(14,7) = HCF(21,14) = HCF(77,21) = HCF(868,77) = HCF(945,868) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 672 > 7, we apply the division lemma to 672 and 7, to get
672 = 7 x 96 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 7 and 672 is 7
Notice that 7 = HCF(672,7) .
