HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 378, 707, 924 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 378, 707, 924 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 378, 707, 924 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 378, 707, 924 is 7.
HCF(378, 707, 924) = 7
HCF of 378, 707, 924 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 378, 707, 924 is 7.
Highest Common Factor of 378,707,924 is 7
Step 1: Since 707 > 378, we apply the division lemma to 707 and 378, to get
707 = 378 x 1 + 329
Step 2: Since the reminder 378 ≠ 0, we apply division lemma to 329 and 378, to get
378 = 329 x 1 + 49
Step 3: We consider the new divisor 329 and the new remainder 49, and apply the division lemma to get
329 = 49 x 6 + 35
We consider the new divisor 49 and the new remainder 35,and apply the division lemma to get
49 = 35 x 1 + 14
We consider the new divisor 35 and the new remainder 14,and apply the division lemma to get
35 = 14 x 2 + 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 378 and 707 is 7
Notice that 7 = HCF(14,7) = HCF(35,14) = HCF(49,35) = HCF(329,49) = HCF(378,329) = HCF(707,378) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 924 > 7, we apply the division lemma to 924 and 7, to get
924 = 7 x 132 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 7 and 924 is 7
Notice that 7 = HCF(924,7) .
