Given numbers are 801, 639, 43, 763

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

Apply this formula for all numbers.

Step1:

LCM(801, 639) = 56871

GCD(801, 639) = ( 801 x 639 ) / 56871

= 801 / 639

= 801

Step2:

LCM(9, 43) = 387

GCD(9, 43) = ( 9 x 43 ) / 387

= 9 / 43

= 9

Step3:

LCM(1, 763) = 763

GCD(1, 763) = ( 1 x 763 ) / 763

= 1 / 763

= 1

So, Greatest Common Divisor of 801, 639, 43, 763 is 1
