Given numbers are 688, 648, 659, 911
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 648) = 55728
GCD(688, 648) = ( 688 x 648 ) / 55728
= 688 / 648
= 688
Step2:
LCM(8, 659) = 5272
GCD(8, 659) = ( 8 x 659 ) / 5272
= 8 / 659
= 8
Step3:
LCM(1, 911) = 911
GCD(1, 911) = ( 1 x 911 ) / 911
= 1 / 911
= 1
So, Greatest Common Divisor of 688, 648, 659, 911 is 1
