Given numbers are 378, 661, 207, 633

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

Apply this formula for all numbers.

Step1:

LCM(378, 661) = 249858

GCD(378, 661) = ( 378 x 661 ) / 249858

= 378 / 661

= 378

Step2:

LCM(1, 207) = 207

GCD(1, 207) = ( 1 x 207 ) / 207

= 1 / 207

= 1

Step3:

LCM(1, 633) = 633

GCD(1, 633) = ( 1 x 633 ) / 633

= 1 / 633

= 1

So, Greatest Common Divisor of 378, 661, 207, 633 is 1
