Given numbers are 344, 784, 247, 840
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(344, 784) = 33712
GCD(344, 784) = ( 344 x 784 ) / 33712
= 344 / 784
= 344
Step2:
LCM(8, 247) = 1976
GCD(8, 247) = ( 8 x 247 ) / 1976
= 8 / 247
= 8
Step3:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
So, Greatest Common Divisor of 344, 784, 247, 840 is 1
