Given numbers are 842, 210, 611, 749
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(842, 210) = 88410
GCD(842, 210) = ( 842 x 210 ) / 88410
= 842 / 210
= 842
Step2:
LCM(2, 611) = 1222
GCD(2, 611) = ( 2 x 611 ) / 1222
= 2 / 611
= 2
Step3:
LCM(1, 749) = 749
GCD(1, 749) = ( 1 x 749 ) / 749
= 1 / 749
= 1
So, Greatest Common Divisor of 842, 210, 611, 749 is 1
