GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(448, 780) = 87360
GCD(448, 780) = ( 448 x 780 ) / 87360
= 448 / 780
= 448
Step2:
LCM(4, 411) = 1644
GCD(4, 411) = ( 4 x 411 ) / 1644
= 4 / 411
= 4
Step3:
LCM(1, 993) = 993
GCD(1, 993) = ( 1 x 993 ) / 993
= 1 / 993
= 1
So, Greatest Common Divisor of 448, 780, 411, 993 is 1
