HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 945, 957, 224 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 945, 957, 224 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 945, 957, 224 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 945, 957, 224 is 1.
HCF(945, 957, 224) = 1
HCF of 945, 957, 224 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 945, 957, 224 is 1.
Highest Common Factor of 945,957,224 is 1
Step 1: Since 957 > 945, we apply the division lemma to 957 and 945, to get
957 = 945 x 1 + 12
Step 2: Since the reminder 945 ≠ 0, we apply division lemma to 12 and 945, to get
945 = 12 x 78 + 9
Step 3: We consider the new divisor 12 and the new remainder 9, and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3, and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 945 and 957 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(945,12) = HCF(957,945) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 224 > 3, we apply the division lemma to 224 and 3, to get
224 = 3 x 74 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 224 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(224,3) .
