Given numbers are 400, 970, 570, 172
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 970) = 38800
GCD(400, 970) = ( 400 x 970 ) / 38800
= 400 / 970
= 400
Step2:
LCM(10, 570) = 570
GCD(10, 570) = ( 10 x 570 ) / 570
= 10 / 570
= 10
Step3:
LCM(10, 172) = 860
GCD(10, 172) = ( 10 x 172 ) / 860
= 10 / 172
= 10
So, Greatest Common Divisor of 400, 970, 570, 172 is 2
