Given numbers are 688, 190, 571, 919
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 190) = 65360
GCD(688, 190) = ( 688 x 190 ) / 65360
= 688 / 190
= 688
Step2:
LCM(2, 571) = 1142
GCD(2, 571) = ( 2 x 571 ) / 1142
= 2 / 571
= 2
Step3:
LCM(1, 919) = 919
GCD(1, 919) = ( 1 x 919 ) / 919
= 1 / 919
= 1
So, Greatest Common Divisor of 688, 190, 571, 919 is 1
