Given numbers are 555, 755, 448, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(555, 755) = 83805
GCD(555, 755) = ( 555 x 755 ) / 83805
= 555 / 755
= 555
Step2:
LCM(5, 448) = 2240
GCD(5, 448) = ( 5 x 448 ) / 2240
= 5 / 448
= 5
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 555, 755, 448, 644 is 1
