Given numbers are 452, 690, 191, 147

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(452, 690) = 155940

GCD(452, 690) = ( 452 x 690 ) / 155940

= 452 / 690

= 452

Step2:

LCM(2, 191) = 382

GCD(2, 191) = ( 2 x 191 ) / 382

= 2 / 191

= 2

Step3:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

So, Greatest Common Divisor of 452, 690, 191, 147 is 1
