Given numbers are 447, 147, 155, 563
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(447, 147) = 21903
GCD(447, 147) = ( 447 x 147 ) / 21903
= 447 / 147
= 447
Step2:
LCM(3, 155) = 465
GCD(3, 155) = ( 3 x 155 ) / 465
= 3 / 155
= 3
Step3:
LCM(1, 563) = 563
GCD(1, 563) = ( 1 x 563 ) / 563
= 1 / 563
= 1
So, Greatest Common Divisor of 447, 147, 155, 563 is 1
