Given numbers are 659, 710, 699, 642
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(659, 710) = 467890
GCD(659, 710) = ( 659 x 710 ) / 467890
= 659 / 710
= 659
Step2:
LCM(1, 699) = 699
GCD(1, 699) = ( 1 x 699 ) / 699
= 1 / 699
= 1
Step3:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
So, Greatest Common Divisor of 659, 710, 699, 642 is 1
