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

Apply this formula for all numbers.

Step1:

LCM(378, 651) = 11718

GCD(378, 651) = ( 378 x 651 ) / 11718

= 378 / 651

= 378

Step2:

LCM(21, 553) = 1659

GCD(21, 553) = ( 21 x 553 ) / 1659

= 21 / 553

= 21

So, Greatest Common Divisor of 378, 651, 553 is 7
