Given numbers are 644, 247, 439, 850
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 247) = 159068
GCD(644, 247) = ( 644 x 247 ) / 159068
= 644 / 247
= 644
Step2:
LCM(1, 439) = 439
GCD(1, 439) = ( 1 x 439 ) / 439
= 1 / 439
= 1
Step3:
LCM(1, 850) = 850
GCD(1, 850) = ( 1 x 850 ) / 850
= 1 / 850
= 1
So, Greatest Common Divisor of 644, 247, 439, 850 is 1
