Given numbers are 893, 625, 784, 645

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

Apply this formula for all numbers.

Step1:

LCM(893, 625) = 558125

GCD(893, 625) = ( 893 x 625 ) / 558125

= 893 / 625

= 893

Step2:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 893, 625, 784, 645 is 1
