Given numbers are 340, 840, 456, 172
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(340, 840) = 14280
GCD(340, 840) = ( 340 x 840 ) / 14280
= 340 / 840
= 340
Step2:
LCM(20, 456) = 2280
GCD(20, 456) = ( 20 x 456 ) / 2280
= 20 / 456
= 20
Step3:
LCM(4, 172) = 172
GCD(4, 172) = ( 4 x 172 ) / 172
= 4 / 172
= 4
So, Greatest Common Divisor of 340, 840, 456, 172 is 4
