Given numbers are 147, 441, 705, 298
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(147, 441) = 441
GCD(147, 441) = ( 147 x 441 ) / 441
= 147 / 441
= 147
Step2:
LCM(147, 705) = 34545
GCD(147, 705) = ( 147 x 705 ) / 34545
= 147 / 705
= 147
Step3:
LCM(3, 298) = 894
GCD(3, 298) = ( 3 x 298 ) / 894
= 3 / 298
= 3
So, Greatest Common Divisor of 147, 441, 705, 298 is 1
