GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 776) = 66736
GCD(688, 776) = ( 688 x 776 ) / 66736
= 688 / 776
= 688
Step2:
LCM(8, 619) = 4952
GCD(8, 619) = ( 8 x 619 ) / 4952
= 8 / 619
= 8
Step3:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
So, Greatest Common Divisor of 688, 776, 619, 805 is 1
