Question

please solve this question and tell me the answer

Answer 1

Answer:

ans is C) 105

Step-by-step explanation:

because possible ans are only 105 and 102 as they are multiples of 3

then we would find HCF of both 105 and 102 with respect to 78

therefore in case of 105&78 HCF is 2x5x3x13x7=2730

Answer 2

Answer: 105

as you know HCF×LCM = A×B

3×2730=78×B

8190=78×B

8190÷78=B

105=B
