Given numbers are 840, 208, 348, 193
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 208) = 21840
GCD(840, 208) = ( 840 x 208 ) / 21840
= 840 / 208
= 840
Step2:
LCM(8, 348) = 696
GCD(8, 348) = ( 8 x 348 ) / 696
= 8 / 348
= 8
Step3:
LCM(4, 193) = 772
GCD(4, 193) = ( 4 x 193 ) / 772
= 4 / 193
= 4
So, Greatest Common Divisor of 840, 208, 348, 193 is 1
