Given numbers are 732, 420, 445, 147
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(732, 420) = 25620
GCD(732, 420) = ( 732 x 420 ) / 25620
= 732 / 420
= 732
Step2:
LCM(12, 445) = 5340
GCD(12, 445) = ( 12 x 445 ) / 5340
= 12 / 445
= 12
Step3:
LCM(1, 147) = 147
GCD(1, 147) = ( 1 x 147 ) / 147
= 1 / 147
= 1
So, Greatest Common Divisor of 732, 420, 445, 147 is 1
