Given numbers are 546, 784, 780, 556
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(546, 784) = 30576
GCD(546, 784) = ( 546 x 784 ) / 30576
= 546 / 784
= 546
Step2:
LCM(14, 780) = 5460
GCD(14, 780) = ( 14 x 780 ) / 5460
= 14 / 780
= 14
Step3:
LCM(2, 556) = 556
GCD(2, 556) = ( 2 x 556 ) / 556
= 2 / 556
= 2
So, Greatest Common Divisor of 546, 784, 780, 556 is 2
