Given numbers are 545, 921, 315, 637
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(545, 921) = 501945
GCD(545, 921) = ( 545 x 921 ) / 501945
= 545 / 921
= 545
Step2:
LCM(1, 315) = 315
GCD(1, 315) = ( 1 x 315 ) / 315
= 1 / 315
= 1
Step3:
LCM(1, 637) = 637
GCD(1, 637) = ( 1 x 637 ) / 637
= 1 / 637
= 1
So, Greatest Common Divisor of 545, 921, 315, 637 is 1
