let a number X which is divisible by 4 and 5 respective gives 1 and 4. Step 1 : now, first divide by 4. we take Y as dividend. when you divide X by 4 it gives remainder 1. 4 | X | Y ____ 1 so X = 4 * Y + 1 --- eq(1) step 2 ; now, divide by 5. we take 1 as dividend because it divides completly. when you divide Y by 5 it gives only remainder 4. 5 | Y | 1 ____ 4 soRelated questions
