Given numbers are 831, 643, 370, 315
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(831, 643) = 534333
GCD(831, 643) = ( 831 x 643 ) / 534333
= 831 / 643
= 831
Step2:
LCM(1, 370) = 370
GCD(1, 370) = ( 1 x 370 ) / 370
= 1 / 370
= 1
Step3:
LCM(1, 315) = 315
GCD(1, 315) = ( 1 x 315 ) / 315
= 1 / 315
= 1
So, Greatest Common Divisor of 831, 643, 370, 315 is 1
