Given numbers are 756, 320, 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(756, 320) = 60480
GCD(756, 320) = ( 756 x 320 ) / 60480
= 756 / 320
= 756
Step2:
LCM(4, 448) = 448
GCD(4, 448) = ( 4 x 448 ) / 448
= 4 / 448
= 4
Step3:
LCM(4, 644) = 644
GCD(4, 644) = ( 4 x 644 ) / 644
= 4 / 644
= 4
So, Greatest Common Divisor of 756, 320, 448, 644 is 4
