Given numbers are 371, 217, 780, 859

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

Apply this formula for all numbers.

Step1:

LCM(371, 217) = 11501

GCD(371, 217) = ( 371 x 217 ) / 11501

= 371 / 217

= 371

Step2:

LCM(7, 780) = 5460

GCD(7, 780) = ( 7 x 780 ) / 5460

= 7 / 780

= 7

Step3:

LCM(1, 859) = 859

GCD(1, 859) = ( 1 x 859 ) / 859

= 1 / 859

= 1

So, Greatest Common Divisor of 371, 217, 780, 859 is 1
