Given numbers are 217, 778, 842, 701

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(217, 778) = 168826

GCD(217, 778) = ( 217 x 778 ) / 168826

= 217 / 778

= 217

Step2:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

Step3:

LCM(1, 701) = 701

GCD(1, 701) = ( 1 x 701 ) / 701

= 1 / 701

= 1

So, Greatest Common Divisor of 217, 778, 842, 701 is 1
