Given numbers are 705, 547, 105, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(705, 547) = 385635
GCD(705, 547) = ( 705 x 547 ) / 385635
= 705 / 547
= 705
Step2:
LCM(1, 105) = 105
GCD(1, 105) = ( 1 x 105 ) / 105
= 1 / 105
= 1
Step3:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
So, Greatest Common Divisor of 705, 547, 105, 445 is 1
