Given numbers are 642, 802, 233, 159
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 802) = 257442
GCD(642, 802) = ( 642 x 802 ) / 257442
= 642 / 802
= 642
Step2:
LCM(2, 233) = 466
GCD(2, 233) = ( 2 x 233 ) / 466
= 2 / 233
= 2
Step3:
LCM(1, 159) = 159
GCD(1, 159) = ( 1 x 159 ) / 159
= 1 / 159
= 1
So, Greatest Common Divisor of 642, 802, 233, 159 is 1
