GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(104, 688) = 8944
GCD(104, 688) = ( 104 x 688 ) / 8944
= 104 / 688
= 104
Step2:
LCM(8, 290) = 1160
GCD(8, 290) = ( 8 x 290 ) / 1160
= 8 / 290
= 8
Step3:
LCM(2, 619) = 1238
GCD(2, 619) = ( 2 x 619 ) / 1238
= 2 / 619
= 2
So, Greatest Common Divisor of 104, 688, 290, 619 is 1
