Given numbers are 690, 278, 835, 709
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 278) = 95910
GCD(690, 278) = ( 690 x 278 ) / 95910
= 690 / 278
= 690
Step2:
LCM(2, 835) = 1670
GCD(2, 835) = ( 2 x 835 ) / 1670
= 2 / 835
= 2
Step3:
LCM(1, 709) = 709
GCD(1, 709) = ( 1 x 709 ) / 709
= 1 / 709
= 1
So, Greatest Common Divisor of 690, 278, 835, 709 is 1
